This list of tips for getting started was posted by Procrastinator's Anonymous member, Milo (original post here). I'm re-posting it, with minor editing, as an article so it won't get lost:
1. Visualisation. Visualise the task being completed and how good it feels to have it off your list and out of your head.
2. Break it down into small steps. (But don't overanalyse; that's another form of procrastination.)
3. Exercise brute-force willpower. Grit your teeth and say, "I'm just going to do it, dammit!"
