Me at the beginning of the project: I should start by writing tests
Me after a couple of days: No time to write tests! GOTTA WRITE THAT CODE
Me now: Oh, yes, I should have written those tests at the beginning

Me at the start of a project: write all the tests, no code goes unchecked.

Me at the end of a project: 🤦‍♂️why does it take 2 hours to run all the fucking tests, which dumbass decided this was a productive way to spend my days adding a single if() and waiting.....
