Ok, so now you've decided not to leave it all for the last minute and have brouhght your books home to study this evening. But you're finding it difficult ti start that one "to do" task. That's because you're afraid it's going to take you too long. What you have do you is convince yourself that you just need to start and do ten minutes' work. Once those ten minutes have passed, you'll be surprised to find that you're now really into the task and don't even want to stop.
