Do something quick and crappy. And let your perfectionism fix it. And... here you are gotten started!

It can be a single word or a instruction that crashes your program at the location that needs to be worked on.

Leave a syntax error for getting started quick tomorrow.

Write down what needs to be done before it leaves your head (but don't make it perfectly structured and clean, a few words on a paper on your desk will do).

edit: For instance, you'd possibly want to fix the missing "n" in this comment. Make this feeling a tool against your procrastination.

edit2: ah, and get the hell out of HN, too.
