Whether or not you know the difference between a hammer and a wrench is irrelevant -- today you need to build something. Creation is a powerful experience, and one that will be especially rewarding. Find something that you can do and do it! Like to cook? Tackle an ambitious dinner menu. Love listening to music? Put together a mix CD or try to record some of you own stuff. Even if it won't win any awards, you'll at least end you day knowing that you did something.
