My experience has often been feeling that something wasn't right and trying to fix it at a low level - variable or function names, length of lines and expressions, organizations in files, things like that. Often I would clean up things superficially but the feeling that something is wrong remains.

Sometimes I come up back after years, having learnt how to organize certain kinds of programs better, and can instantly see that the problem was much deeper than that. I now think that as a rule of thumb, if it is hard to make a piece of code tidy at a superficial level, there is a deeper underlying issue. If I manage to find a good architecture, I try to keep the bad code as minimal as possible instead of investing more time in a dead end.
