I would think the most important thing to do first is to stop and think about the logic of the code. Plan a small and simple roadmap in your mind, or on paper if your mental memory is low. This will save you a lot of the try-and-fail attempts, and even better, before you write a single line of code, you have a general idea of what it is that you're doing and how it is that you're going to be doing it.
