I always try to write easily readable code that is well structured.

I face a particular problem when I am messing around with something new. I keep changing the code, structure and so many other things. In the end, I look at the code and am annoyed at how complicated it became when I was trying to do something so simple.

Once I've completed something, I refactor it heavily so that it's cleaner. This occurs after completion most of the time and it is annoying because the bigger the code the more annoying it is the rewrite it.

I am curious to know how people deal with such agony, especially on big projects shared between many people ?
