Hey, world: Clean out your inbox!
I subscribe to, and routinely evangelize about, Merlin Mann's "Inbox Zero" technique of email filing. It's a simple way of organizing your email that results in fewer headaches. Basically, if you can't get something done in two minutes, file it for later. Once you read an email and there's no further action to be taken, delete it or archive it. Then use the time you save to look smugly down at all those people who use their Inbox to store all their emails.
