I've been at the office until the wee hours of the morning. I don't know how people can still write coherent code at that point. My mind starts tripping under its own weight at the four-five hour mark. I usually can't make it past 2 or 3 hours without a break. Those times when I was hacking away like I was doing something so important that the world just couldn't wait for it... well I'm pretty sure I was at that office so late simply fixing the stupid mistakes I was making just hours before because I was too bleary-eyed, tired, uncomfortable, and frustrated to be effectively working. In a few years you may or may not realize that there's more to life and that you won't get your youth back.
