If you are not yet familiar with the concept of Inbox Zero, you need to check out this video presentation by Merlin Mann.
The idea behind Inbox Zero is that you should not be using your email inbox as a storage or filing location for your email. The concept ties very closely with David Allen’s Getting Things Done concept.
Basically, Mann advocates a ruthless processing of your email on a schedule that you control. Process each email and then get it out of your inbox. I know this concept is an anathema to many people. However, I have found getting rid of emails from my inbox to be very liberating. I encourage you to watch this video and try to follow Mann’s suggestions.
Don’t just take my word for it either. Michael Hyatt has written before about how much imposing email controls has improved his productivity.
