I've been tracking tracking my work down to the minute for the past seven years. (timer and log book.) I started out trying to get to five "hands on keyboard" coding hours a day, five days a week, and realized that it was unrealistic after the first few years. Four hours of coding time, five days a week works for me. If I'm a little under I work Saturdays, if I'm a little over I take off early on Friday. Unless I'm sick I put in 20 hours of coding a week. You would not believe how nice this way of working is.
