Everyone is different, so what works for you may well be different than what works for everyone else. You may work best in the morning or late at night. Take advantage of your own strengths, and find ways to compensate for your weaknesses. Experiment with listening to music while you work. I use the free WinAMP player, which can stream commercial-free radio directly to my computer all day long with a variety of channels to choose from. I find that classical and new age music, especially Mozart, is terrific for web development work. But for most routine tasks, listening to fast-paced techno/trance music helps me work a lot faster. I don't exactly know why, but I'm twice as productive when listening to really fast music as compared to listening to no music. On the other hand, music with vocals is detrimental to my productivity because it's too distracting. And when I really need to focus deeply, I'll listen to no music at all. Try a simple experiment for yourself, and see if certain forms of music can increase your productivity. For me the difference was dramatic.
Whenever you come up with a wacky new idea for increasing your productivity, test it and see what effect it has. Don't dismiss any idea unless you've actually tried it. Partial successes are more common than complete failures, so each new experiment will help you refine your time management practices. Even the ongoing practice of conducting experiments will help condition you to be more productive.
