When I was in startup mode, the first 4 months was 10-12 hours of programming, 7 days a week. I may not have showered every day, but I sure as hell made forward progress. It was a remarkably "pure" feeling. Turns out that's not a sustainable pace. Not only do you run out of stamina, you run out of ideas. Now I work at a medium-sized but incredibly fast-paced company. I write code every day. But since I work on performance and not a particular feature, my checkins tend to be small but well-chosen. A few people I work with have net-negative lines-of-code scores.
