One small habit that may help is to quickly glance over your Projects list a few times a day and notice what thoughts, feelings and your attention go when you look over them.
As David says, notice what has your attention and give that it's proper attention. Is there something you're avoiding to do? Friction like that is usually a sign that there's an unfinished thought process or commitment that isn't clear.
On the flip side, if you look over your whole project list, and you decide the best thing to do is something else not on your list (and you're comfortable with that), then that's fine to. It's not about getting a bunch of stuff done. It's about being comfortable with your choices.
