Leave behind processes better than the ones you inherited.

You inherit processes that someone else made under pressure, with less information than you have. Most people work around the bad ones and hand them on unchanged, because fixing them is nobody’s job. Leaving them better is a small, unrewarded act that quietly improves every person who comes after.

Pick the one inherited process that annoys you most and spend an afternoon actually improving it rather than tolerating it again. Nobody will notice. It will still be better for years.
