When working on a programming side project, don’t aim to make it “perfect”, just make sure it is good enough and well architectured, but don’t get obsessed with “perfection”, and each day make sure to add some improvements here and there, and fix some bugs if needed.. and after multiple iterations and consistent mini-improvements, you will end up with a code that you should be proud of.

but keep in mind that this also applies the other way around, if each day you introduced minor bugs and hacks and workarounds to make the code work, after a while you will end up with a lousy codebase and a lot of technical debt.
