I think this kind lifestyle could take a toll on your lifespan. That being said, I get the part about the feeling letdown with yourself. I set a lot of goals, made elaborate to-do (or rather, to-don't) lists, and instead of executing I spend hours crunching through articles on HN, reading Wikipedia, etc. I've been trying hard to let go of what I see in myself as an "information addiction". I've cut short the hours I spend on HN (but not always), and replaced some of my online reading with more high-quality reading on my Kindle. One thing I've found is that once your start working on a project, keeping on going is easy. It's just the initial static friction that's hard to overcome. Force yourself to do that project, and in minutes you'll be enjoying it!
