In order to be most productive, you need blocks of uninterrupted time to focus on vital tasks that add the most value to your business. Excessive in-box viewing wastes time and adds to e-mail overload. One time-management software firm estimates the average office worker checks his in box 50 times a day; I suggest five. Even if you work a job that demands that you stay on top of your e-mails, that five viewings allow you to see your e-mail about every 90 minutes. (Hint: Wait an hour and a half after getting to the office before you open your in box.) Schedule the specific times during the day that you will check your in box, and stick to it.
