Starting over from scratch instead of trying to fix

This is mainly just cause I’m inexperienced and don’t have the foresight to think about maintainability but I’ve been working on a project for the past month or two and have restarted like 5 times. I get to a point where things are so disorganized and it’s hard to make changes and it feels easier to just start over rather than try to fix what I have. Mainly just a rant but curious to hear if anyone else has gone through a similar experience and whether anyone has strategies for writing maintainable code.
