Reconnect to old friends or make new friends. While there's a certain masochism about sacrificing everything on your startup vibe on HN, if you want to do startups/entrepreneurship for more than a single deathmarch to burnout, you need to keep things sustainable.

Keep training jiu jitsu, maintain social relationships, chase girls (or boys or whatever) and make sure you allocate time to keeping yourself healthy - physically, mentally and emotionally. For most people that means a social network (not the facebook kind) to keep you grounded.

Otherwise, pick a hobby, preferably one that is social but where you won't be tempted to spend escalating time on it. Sports league, dance, improv, whatever.
