GTD Calendar: +5

There are many parts of Getting Things Done. Some I find more useful than others. One I have adopted is Allen's calendar management. Specifically:

1. Put everything with a specific time (i.e. has to be done at 3:30 on Tuesday) in the calendar.
2. Put nothing that doesn't have to be done at a specific time in the calendar.
3. Review your calendar for the day first thing in the morning.

This is a huge organizational help, and avoids missing a lot of timed events I would otherwise miss.
