I was doing a startup with a high achiever, I estimate ~160 IQ or higher; he worked 7 days a week, at least 12 hours a day, but often 16 for at least 20 years.

I was doing a startup with a high achiever, I estimate ~160 IQ or higher; he worked 7 days a week, at least 12 hours a day, but often 16 for at least 20 years. He was a step-change smarter than me; PhD in Chem E. from top school, brilliant computer scientist... the only time I saw him relax is once he played Sonic the Hedgehog for like 10 hours straight. He fried his motherboard... his wife texted me one day... he's in a coma... 12 days later he emerges from the hospital with amenesia... that was years ago, still has amensia, can't create new long-term memories, can't work, etc. One thing that helped me during burnout is reading biographies, idk why it helped, but I'm passing it forward.
