This was exactly my thought. When I was in my twenties, starting my first company, I hammered myself every time I failed to deliver on my TODO list. Today, I'm far more introspective. If there's something that's dying on the vine, I want to know why that thing is apparently not very important to me.

Spend time figuring out what's really important and make sure your TODO list is full of those things. The unimportant stuff? Outsource it or make changes so that you don't have to have those things on your list.
