I agree with the spirit of the post. We all need to do better at saying no and shutting down unsuccessful projects. But I will say that my your brain and your gut have utterly failed my in the past. The whole point of todo lists is to manage the unimportant things. Just because your brain views something as unimportant doesn't mean it doesn't need to (eventually) get done. We all procrastinate. I'll say that there's value in at least knowing what you're procrastinating about.
