Jeff should really go to sleep

Sometimes it feels like everyone else out there has a textbook to life with all the theorems explained, and I just got a handful of axioms and have to derive the rest. Except that the textbook was put out by a less than competent publisher, and is rife with confusing language and out-and-out errors, so I really am better off figuring it all out myself, even if I make the occasional mistake and spend a lot of time reinventing the wheel.
