Don’t just manage your time, manage your energy also. When I am creating my list of things to do for any given day I try to schedule them according to my energy level. I know that I am most creative in the morning so I try to do all of my writing for the day as soon as I get up. I also try to attend webinars and work on web/techie stuff in the morning. If I try to do it later in the day, I am not able to concentrate and I don’t get as much done. Are you a morning or an eveing person? When is the best time for you to do things that are hard, things that you don’t want to do or things that require a high level of concentration? Schedule tasks according to your particular rythm and watch your productivity increase.
