Hey Udet, I've got another helpful hint on how you can save time. When looking for books to read, make your entire purchasing decision based on whether or not you like the artwork on the cover.
Ooh, and to save time dealing with people, just put together a helpful list of preconceptions about each of the major races (eg, black, hispanic, etc) and just use those when dealing with them. This will save you the hassle of having to listen to them.
