Give yourself the gift of uninterrupted time. It can be the first hour of your day. Or the last hour. A lunch hour. You want time free from phone calls, visitors, mail, things to read. Unplug the phone if you have to. Lock your door. Put a sign on it that warns people of the consequences of entering. Do what you have to and watch the results. One hour of uninterrupted time can double a person's productivity for the day.
