I have always been a big fan of simplicity. Less is more. It works for me and, honestly, I think it would work for anyone who would make the effort to streamline areas of their life. Once the initial streamlining is done then it is easy to live simply. Case in point... your inbox. Even if you are not willing to admit it, clutter is stress-inducing and the clutter in your inbox can become a big stressor. First of all, if you are going to maintain an e-mail address then you should be prompt with your responses to others. Very unprofessional to drag your feet with correspondence. The times when I have been horribly slow responding to others is when my inbox is out of control. Tim Sanders recommends (here) having your own inbox handicap and keeping the number of e-mails in it at or below that number. My handicap is 20 and when it gets over that, I take a few minutes to answer, delete or file what is in there. Very simple, really. Give it a try and see if it doesn't destress an area of your life.
