Doing it right once takes an hour. Doing it fast and redoing it takes three.

Speed at the start usually borrows from the middle. Rushed work carries small errors that surface later, and by then fixing them means undoing what got built on top, which is where the extra hours go. The fast version is genuinely faster only when nothing depends on it afterward.

Before starting something, ask whether anything will be built on top of it. If the answer is yes, slow down at the foundation and let the later parts move quickly instead.
