Getting started is the hardest part

Whenever I have a big project to do, or any homework for that matter, I find myself procrastinating getting started for the longest time. Hours, days, weeks.... Even with a deadline, I will put off that starting moment as long as I can. I don't know why, once I do start I plug along and it's not that bad. I sometimes even enjoy it! But for whatever reason I just hate to start something...
