Here, I've got a more comprehensive list of things that I have in my room and don't know how to use. I wish I had time to learn how to use these things. It troubles me to think of all the money I've spent and they are of no use to me. This weekend I'm going to sit down and learn to use them all. I tried to put them in alphabetical order for your reading pleasure.
