Always remember, however, that there’s usually a simpler and better way to do something than the first way that pops into your head.

Premature optimization is the root of all evil.

TeX has found at least one bug in every Pascal compiler it's been run on, I think, and at least two in every C compiler

AI has by now succeeded in doing essentially everything that requires 'thinking' but has failed to do most of what people and animals do 'without thinking'-that, somehow, is much harder.

By understanding a machine-oriented language, the programmer will tend to use a much more efficient method; it is much closer to reality.

Programs are meant to be read by humans and only incidentally for computers to execute.

If you optimize everything, you will always be unhappy.
