Ask HN: Most effective time management strategies?

There are times when I find the mountain of information in the world overwhelming. Usually it's at a time when I am interested in a wide array of topics and want to pursue them all at once. However as you all probably know spreading yourself too thin usually results in information overload and not really learning very much. How do you all manage your time? There are so many things that have to be done in a week and usually within a single day. Work, family, interests, learning, reading, practice, not to mention sleep! At the moment I'm juggling 2-3 books, a few papers, working in and out of the office, trying to make it to the gym, get more than 6 hours of sleep a night and making my best effort to practically code too. I wont include the time spent reading what is posted on HN. I hope you all will take the time to respond as I think those that are capable of managing their time efficiently get more done and accumulate more knowledge. Zed Shaw really comes to mind.
