Use the FAD (file, act, delete) principle to get organized. This works great with email. When you go through your inbox be sure to file the message, act on it or delete it right away. Do not read it and leave it in your inbox. If you do not have time to file, act or delete then wait until later to read your messages. FAD saves you time because you only handle each message once. Give it a try.
How do you handle your inbox? Could the FAD system save you time?
