My startup failed in 2017. Leading up to that I had several panic attacks. Lots of things stressed me out: work, the news, money, etc...

I spent a lot of time after that reflecting on what went wrong and part of it was a dismantling of my ego, and a lot of meditating and reading philosophy.

The subtle art of not giving a fuck... And lots of stoicism, Marcus Aurelius, Aristotle...

Love fate

The only things in our control are our perception and our choices.

God, grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference

I don't really consider myself religious, but I learned to value the useful and still relevant parts of several religions.

Then I practiced... Lots of deliberate practice. Meditation, exercise and practiced deliberate choices and perception.

I don't get nearly as stressed anymore.
