I would second this one, to add, just finish what you start. (be reasonable with what you start) e.g. I want to speed run Super Mario Brothers using code Just finish at least a working version, screw the quality of the code, screw the results — just make it run/work once, then quit afterwards if you feel like it. Side Tip: Less talk about what you are doing before you've did it, generally™, helps to complete it. (completely anecdotal)
