How to Solve it

There's a lot of useful value here - even though the writing style and target audience is a bit too narrow:

- has some assumption of a teacher/student context
- assumes a more mathematical context
- generally assumes an academic context is most parts

But it's a good articulation of how to solve problems.

Wherever I first read this in college it freaking blew my mind. I read it a few times. Had a profound impact on my life etc etc. I hadn't really thought about heuristics one might use for divining proofs. I used to try to just think as hard as I could and maybe I'd figure out the answer. But this guy has a whole methodology for it and it makes sense. I printed out the summary and put it on my wall behind my desk so that it would watch over me and the wisdom would flow out.
