In my mind I'm a lazy person. My good hours are in the morning, and after that it only goes down. Right in the afternoon it's really hard for me to get anything done. When I was studying at the university for exams, I learned more than 50% before noon, rest in the afternoon, and at 8pm, I was unable to keep anything in my head. Now is the same, but if I haven't worked that much during the day, I can still crunch out some good code at 9pm. If I worked during the day, no way I can do that. Yet, when I look back, I always had great reviews at my jobs. Some managers considered me more productive than others who I thought were more productive. Next to my full-time job, I take care of our 3 kids together with my wife, and I'm programming a side project http://rpgplayground.com http://rpgplayground.com. I always had projects in my spare time. Some people with kids ask me were I can find the time. Yet, I still feel lazy all the time. In the weekends I'm beat. Sunday is terrible, but due to that I'm "super" productive on Monday (relative to the other days ;)). I think it's hard to know by yourself if you are productive or not. Being productive 60+ hour per week? I highly doubt that. I even doubt begin 40+ hours productive per week. With productive I mean crunching out good code, while being in the zone. I think a good day is being productive max 6 hours, on average 4. But it is impossible to do that in one go, and you also can't do something else productive during your resting time. If you look at athletes, they also don't train more than 6 hours in a day. My good days are when I'm feeling energetic, positive, and am passionate about a clear goal, and like the 'zone' that I'm in, the problem I'm solving. Also, a good nights sleep can do wonders!
