I *try* to do every problem, and how long it takes varies on how well I
took notes on the chapter (it ranges from simple bullet points to long
rewrites of the passage in simpler terms).

Some problems I can't do right away (e.g. the question at the end of
chapter 2 I think that asks you to patch up the simple shell so it
includes pipes, and so forth), so I outline a few thoughts about it
then sleep on it. Then I try programming it, seeing if it works. If it
did, huzzah; if not, back to step one. So in short, my algorithm is:
1. Write problem down.
2. Think very hard.
3. Solve problem.
This is the "Feynman algorithm"
