working in a single file, not separating stuff properly. I don't do that for work related stuff, but I'm very lazy when it's a personal project

It should be the opposite way imo.

I got the opposite problem currently
Got handed a project that is so unbelievable spread out that it becomes spaggeti again. I'm talking files with around 10 functions, each mostly 3 to 4 lines calling eachother, and a large config file.
I've since rewritten it in a single file with like 200-300 lines.

Maybe later on I split that out again but for now it's much more clean and understandable this way
