Ask HN: How do you get over perfectionism/overthinking in hobby projects?

I have many empty repositories at Github which were supposed to be ML softwares. The reason is that whenever I started to write code, I was obsessed with making it abstract, extendable, modular, easy-to-read, ... (Rare thing among ML softwares) So most of my time was spent on designing modules without writing any actual ML code! And then I got disappointed and let it go. Any suggestion on how to cool down this obsession so I can write at least some actual working code for god sake?
