Don’t let the perfect be the enemy of the good. That said, it’s vanishingly rare that I’ve regretted designing something for long term use rather than just hacking it together.
Taking the extra time to document stuff, to add guard rails/error handling, to make a piece of script easier to re-use, to actually plan something rather than building it as you go… almost always a good use of time.
The fuck you mean, mossy?
