I would like to add another dimension to this question, how do you pre-founders manage work life balance? (Pre-founders being those who are still working their day jobs, hacking away at nights/weekends)
Selective neglect: My closet is a mess. So is my basement. I spend time with my wife and kids.
Efficiency: I keep my priority list in front of me so I'm always coding the most important things. I use a Lisp dialect so that I can make effective use of short coding sessions. A lot of my progress in the past few years has been during 35-minute train rides.
