"haste makes waste" is an important aphorism against high time preference.
it's not just going quickly, it is also going hard. many times easing back on the pressure on things works much better.
peeling stickers off thing, for example. if you just hurriedly try to remove it, you wind up tearing the paper apart, and then spend 5 minutes scratching off the rest and it's still not clean.
meanwhile, if you just ease off the pressure a little, and use your nail to gently persuade the sticker to lift along a growing edge, you can get the thing off in one piece, or at least get most of it off in one piece, and probably take less time, and leave less sticker residue.
same goes with programming. most tech debt comes from hurrying through a step in the process, which leaves a mess that takes longer than it would have taken if you'd done it more slow and systematically.
