A mindset is a default way of seeing the world
0:04
And our mindsets influence so many things in our lives. They influence our decisions
0:09
They influence our relationships. They influence the way we think and even the way we feel
0:14
When we're not aware of our mindsets, they can impact the direction of our life
0:18
the path that we're taking without us even realizing it. Being aware of your mindsets is the difference
0:23
between living a conscious life where you're making choices in accord with what you actually want
0:29
and going where you actually want to go versus being on autopilot
0:32
and having those mindsets subconsciously drive all of your decisions. The great thing about mindsets is that they can actually change
0:40
But the first step is to make them conscious. The experimental mindset
0:49
I divide my life in two separate chapters. In the first one, I had a very linear approach
0:56
that was driven by traditional definitions of success. I did my best to do well in school
1:02
and then I got a good job at Google and then I tried to climb the corporate ladder
1:06
getting a promotion, working on the best projects possible. And from an external standpoint
1:11
I should have been happy, but I wasn't. Instead, I was feeling empty inside
1:16
I was both bored and burned out. I left my job at Google thinking
1:21
that I should try to do something different and not realizing that I was following
1:25
yet another script of success, I decided to start a startup. And again, I didn't find happiness there
1:30
by following this idea of success that everyone around me was following. It's only when my startup
1:36
failed and that for the very first time in my life, I didn't have a clear idea of what I was
1:41
supposed to do next in order to be successful that I finally asked myself, what is it that I wanted
1:46
to do? What would make me happy, even if I forgot about the traditional definition of success
1:51
And so I went back to the drawing board and I started thinking about what I was curious about
1:57
Again, not based on traditional definitions of success. What were topics I would be excited to explore even if nobody was watching
2:05
And for me, that was the brain. I had always been fascinated with why we think the way we think and why we feel the way we feel
2:13
So I decided to go back to university to study neuroscience. I completed my graduate studies and I got a PhD in neuroscience
2:20
Throughout this journey, I decided to learn in public. And this is how I started my newsletter
2:25
Every week, I would pick a topic that I had discovered in my studies in university, and
2:30
I would take those neuroscience insights and turn them into practical tools that I would
2:34
write about in the newsletter to help other people apply them in their life and work
2:39
This tiny experiment of starting to write online and sharing what I was learning in public
2:45
was the beginning of my work of trying to understand how we can live more experimental
2:50
lives. There are three subconscious mindsets that get in the way of us living happy conscious lives
2:57
These three mindsets are called the cynical mindset, the escapist mindset, and the perfectionist
3:02
mindset. The cynical mindset is when we have lost all curiosity and ambition in life and we're
3:07
actually sometimes even making fun of earnest people who still have this high level of curiosity
3:12
ambition. When we're cynical, we feel like there's no point trying because we're in survival mode
3:18
all the time. So things that we might be doing instead is doom scrolling, sitting on the sofa
3:24
going through negative news, being stuck in this cycle, and then maybe even spending a lot of time
3:29
and energy discussing and debating those negative news with other people In the escapist mindset we still curious but we have decided to let go of our ambitions With the escapist mindset we trying to do everything we can to escape our responsibilities
3:43
That can take the form of retail therapy, binge watching, or dream planning, or next vacation
3:50
instead of doing something right now to change our lives. In the perfectionist mindset, we try to escape uncertainty through work
3:58
So we have high ambition, but low curiosity. that might look like self-coercion, overworking ourselves, toxic productivity
4:06
Our goals are driving all of our decisions. We feel like if we manage to achieve that goal, if we manage to be successful, then we'll be happy
4:14
You can picture those three subconscious mindsets on the 4x4 metrics where the two different factors are curiosity and ambition
4:22
In the case of the cynical mindset, it's low curiosity, low ambition
4:26
For the escapist mindset, high curiosity but low ambition. And with the perfectionist mindset, you do have high ambition, but you have decided to let go of your curiosity
4:36
Those mindsets are actually very fluid and they might change depending on our situation and different triggers and different ambitions that we might have at the moment
4:44
This is actually really good news because that means that these mindsets are not fixed personality traits
4:50
We can change them by becoming aware of them and then making the decision to change our mindsets
4:56
This is something we can achieve. There is an alternative to those three mindsets, which is called the experimental mindset
5:03
This is a mindset where your curiosity and your ambition are both high
5:08
In an experimental mindset, you're open to uncertainty. You see it as an opportunity to explore, to grow, and to learn
5:15
Having an experimental mindset helps us completely reimagine a relationship to ambition and to goals
5:21
When you have an experimental mindset, instead of chasing those linear goals that give you the illusion of certainty, you're open to designing experiments
5:30
Instead of trying to get to a specific outcome, you start from a research question
5:35
Anytime you don't understand something, it doesn't create fear. It creates curiosity
5:40
Having an experimental mindset means seeing failures as data points that you can learn from
5:46
It means being open to making mistakes because you know you're going to learn from them
5:50
It means embracing the fact that you might not have a plan, that you don't know what's coming
5:56
And this is great. It means that you can design your life in a way that is conscious and connected
6:01
The idea of cultivating an experimental mindset is based on the scientific method
6:06
And this is very simple. First, you start by observing your current situation, by looking at the world around you
6:13
Then you ask a research question and you design a tiny experiment to collect data, which you can then yze
6:20
Based on those results, you can decide what your next step is. What's great about that is that even though you don't know where you're going
6:27
you can trust that you're going to grow through each cycle of experimentation. To design an experiment, you need to commit to curiosity
6:34
A great way to do this is to design what I call a pact. This is a commitment device where you say, I am going to run this experiment
6:42
The way it works is that you choose one action and you then decide on a duration
6:47
and you say, I will perform this action for this specific duration. Why does it look like that
6:54
There are several reasons. The first one is that when a scientist designs an experiment
6:58
they design in advance on the number of trials. You don't simply stop in the middle if the results
7:04
don't really look like what you expected. You collect all of the data. And once you have all
7:09
of that data you can yze it and decide what the answer is The second reason is that it allows you to notice when you falling prey to the maximalist brain You can make sure that you keeping your experiment tiny enough
7:22
that you're actually going to complete it by choosing a duration that is reasonable
7:26
something you can actually achieve so you can collect all of the necessary data. A pact is
7:31
purposeful. It needs to be something you care about. And what's great is that when each pact
7:35
you design has purpose imbued into it, you don't need to have a grand purpose in life
7:40
A pact is actionable. This is something that you need to be able to do right now. You don't need
7:46
extra resources. You don't need help from other people. This is something you can try straight
7:50
away. A pact is continuous. This is something that you need to do regularly. Again, you decide
7:56
on the duration, the number of trials, and then you say, I'm going to do this action for two weeks
8:02
I'm going to do this action for two months. I'm going to do this action for one year
8:07
And finally, a pact is trackable, not measurable. You don't need complicated metrics
8:12
You only need to be able to say whether you did it or not. Did you do the action
8:16
Did you perform it? Yes or no. That's the only tracking you need
8:21
A pact is not a new year resolution. This is not something that you decide on that is very ambitious at the beginning of the year
8:28
and that you're going to abandon. This is something small and achievable that you can start doing at any point during the year
8:35
A pact is not a habit either. The difference between a habit and an experiment is that with a habit
8:40
you're very clear that this is something that's going to be good for you. And so you commit to it for an indefinite amount of time
8:46
For example, you say, starting today, I'm going to go to bed at the same time
8:50
Whereas with an experiment, you're not quite sure whether this is going to work for you or not
8:56
You're going to test it. And so you're going to say, I'm going to go to bed at the same time every night for two weeks
9:02
And then only I'm going to decide whether this is good for me or not and whether I want to turn it into a habit
9:07
And a pact is not a KPI, an OKR, a performance metric, or however people call them in the corporate world
9:14
It's really just about learning something new. It's not about being successful or getting to a specific outcome
9:21
Once you've completed your pact and you've gone through the entire duration of that data collection phase, you can finally look at the data
9:28
I highly encourage you while you're running your pact to take little notes
9:33
It can be very simple, a few bullet points on your phone, something in your journal
9:38
but just to keep track of whether you did it or not and how it felt. Based on that, you can make the decision to either persist with your pact, as is, because it works for you
9:47
You can also pause it if you feel like that's not really something you want to keep going with
9:52
Or you can pivot, which means making a little tweak and changing something
9:56
before you start your next cycle of experimentation. A lot of us tend to only pay attention to external data or internal data
10:03
when we're yzing our experiments. For example, we might only look at the external metrics of success
10:09
or only at the internal feelings that we might be experiencing. But both are very valuable in order to make the right decision
10:17
when it comes to your next steps. The external signals might show you whether this is something
10:21
that is worth pursuing in terms of financial success or career or any ambition that you might want to explore. But the internal signals are also very important
10:32
There's no point being successful externally if it feels horrible to work on this project
10:37
And equally, if it feels really good, but you have no way to sustain yourself with this project
10:42
it might be worth reconsidering the parameters to find a way where you can have an overlap
10:47
between external success and also internal positive feelings and emotions of working on this Let me give you an example I designed an experiment where I wanted to explore whether I wanted to become a YouTuber
11:00
This was something I had noticed a lot of friends around me doing. And they seemed to have a lot of fun
11:05
That piqued my curiosity enough that I wanted to give it a try. So I designed a pact
11:10
And as said, I'm going to publish a video every week until the end of the year
11:15
Very simple pact, which I completed. it. Every week I published a new video. At the end of my pact, I looked at the data. External data
11:24
pretty good. Looking at the traditional metrics of success of a YouTube channel, I got to a good
11:29
number of subscribers, a lot of positive comments. People seemed to like the videos and I even had
11:34
some people reaching out and asking if we could collaborate together. But internal data. I actually
11:41
did not enjoy producing these videos. Every week when I had to sit down in front of the camera
11:46
I was dreading it. I love having face-to-face conversations with people and seeing their
11:51
reactions in real time, but just looking at a camera with no feedback whatsoever was very
11:56
uncomfortable for me. As a result, every week I was procrastinating for so long, every time I had
12:01
to film a video. I felt deeply anxious and I was not even able to work on anything else on those
12:07
days where I was supposed to film. This is a typical example showing why it is so important
12:12
to considering both the external and the internal signals before making a decision
12:17
Based on this, even though the YouTube channel was fairly successful in such a short amount of time
12:22
I decided to stop. I realized that I was not going to be a YouTuber and I preferred to keep on writing my newsletter
12:29
You can run tiny experiments in all areas of your life. In work, for example, you could say
12:34
I'm going to write an internal newsletter every week for the next six weeks
12:38
where I share the most interesting links that I find. In relationships, you could say, I'm going every Sunday to sit down and send a note to a friend I haven't talked to in a while
12:48
And even when it comes to your health, you could say, I'm going to go for a walk for 20 minutes for 20 days to see how I feel at the end of that experiment
12:56
With an experiment, you're not making any assumptions as to whether this is going to work for you or not
13:01
A habit that a friend has, for example, going for a run three times a week might not be that good for you
13:07
Maybe when it comes to your health and body movement, you prefer dancing or something else
13:12
That's why it's interesting to run an experiment before committing to a habit
13:17
When it comes to running, for example, you could say, I'm going to try that. I am going to go and run three times a week for three weeks, not for the rest of my life
13:26
And at the end of the three weeks, I'm going to decide whether this is what I want to keep doing
13:30
or if I want to experiment with another way to move my body
13:35
In essence, committing to curiosity is ensuring that you're going to live a life that is intentional
13:41
that you're going to live your life, not the life that other people are expecting you to live
13:46
Curiosity keeps you adaptable and nimble in an ever-changing world. It ensures that you stay open to new possibilities
13:53
And frankly, it just makes life more fun. This all might sound philosophical, but there's actually a lot of neuroscientific research
14:00
showing that when we experience thirst for water, the same parts of the brain activate
14:06
than when we experience thirst for information. So when we say I'm thirsty for knowledge
14:11
I want to learn more, I want to know more, we couldn't be more right. And thinking about your own mindsets
14:16
developing this self-awareness is really just a way to direct this curiosity
14:21
towards the things that you actually want to do with your life. Want to support the channel
