Use a timer to schedule breaks.
Estimate the amount of time you think you can stay focused on work. Maybe it’s an hour, or maybe it’s 10 minutes -- it will vary, depending on your state of mind. Set a timer for that interval and try to stay on task. Then take a two- to five-minute break. Repeat the cycle during your work session. Use your breaks to recharge: Eat a healthy snack, drink some water, use the bathroom, take a quick walk, listen to music. Avoid checking e-mail or logging onto the Internet. You know what will happen.
