So, pick your battles and don't sweat the small stuff.
For want of a nail
You write some garbage that's "fast enough" for you, then the next guy writes some garbage on top of yours that's "fast enough" to collect his paycheck, etc. Eventually some poor schlub has a program that runs forever, benchmarks it to find a flat profile, tries to fix your stuff, and finds layer on layer of "good enough" design.
If you think a bit and write something decent, other people will be able to reuse your code. However, if you generate garbage, some poor fool will just have to rewrite it later. "Whatever you thought of first" and "whatever seems clear to you" are not necessarily decent.
