People always say that good style is important

People always say that good style is important, but when they go out of their way
to use clear techniques and make their programs readable, they seem to end up with
less efficient programs. Since efficiency is so important, isn't it necessary
to sacrifice some style and readability?

It's true that grossly inefficient programs are a problem, but the blind zeal
with which many programmers often chase efficiency is also a problem. Cumbersome,
obscure programming tricks not only destroy readability and maintainability, but
they may actually lead to slimmer long-term efficiency improvements than would more
appropriate design or algorithm choices. With care, it is possible to design code
which is both clean and efficient.
