People are intimidated by large tasks because they're thinking about the entire task all at once. This blog post points out the key element which is that you have to think about small easy tasks instead. Once you move your focus to small easy sub-tasks, it becomes much easier to start doing them because it's not hard.

The truth of the matter (especially with ADHD or HFA people) is that once you even start doing a small sub-task, you then quickly become addicted to or motivated to getting more and more of it done, and before you know it, you've gotten many sub-tasks done or even accomplished a large task you'd been procrastinating about.
