You don't need links. Just exhaust yourself. You know how.

I was in the same boat - solo founder, working 14 hour days, incredibly stressed. Exercise and avoiding alcohol, drugs, and shitty food is the key.

There is a certain level of stress that I think can't be dealt with. When you reach that limit, you have either step back and curtail what you're trying to do, or just push forward and get through it.

I think it is important to find something you enjoy. I tried to go to the gym and hated it this led me into a situation that I was essentially punishing myself for trying to take care of myself..

Currently I take figure skating classes, inline skate, swim, freedive, kayak, and do yoga(yin and pranayama). I might have overshot a little, as my startup (more of a side project atm) is suffering a bit ;)
