Wow, what promped you to give it all away?
Ultimately, it started feeling like I'm paying to become mentally weaker so now I opt to live a life with nothing to lose.
After I no longer care about my income, I can now fearlessly call people out on their bullshit at work and challenge their decisions. It helped me focus more at work and make the right decisions instead of the easy ones.
Imo, if you are truly happy, you can find happiness no matter how bad your situation is. So I don't care about the distant future. I optimize for the impact I can make today.
