"Do the simplest thing that could possibly work" - then move on to the next thing. This is going to be painful for you to not stay to "perfect" it (it will take some courage) but bear in mind the following: It's surprising how often the extra bits you were worried about turn out to not actually occur, once you've learnt more from the initial version, you've understood it better and therefore designed a better approach. The first version is to understand the problem. The next version (a rewrite) is to understand the solution. Call them "exploratory drafts" if you like.
