Like writing, code gets better with mulling over most parts (for a long time) and rewriting a lot after insights were properly formed. When you start something, you are exploring; how can you expect that that code will be anywhere close to an ideal situation that time? People say refactoring but in my opinion that is not radical enough; you will be able to redo problems you encountered by maybe completely re-architecting the solution. This luxury is not really a thing many people can afford ofcourse; we just make stuff work well enough to get paid. And it shows.
