The author touches on a very important point here by distinguishing determination and grit. I think most of us, myself included, will use sheer willpower and determination to perform tasks on a super-human level, e.g., work 20 hrs/day, stop reading unnecessary emails, stop twittering, exercising, etc. However, performing these tasks could be overlooking the big picture. Sure we can push ourselves to work 20/hrs a day and be productive, but to what end? I think true success yields from constant introspection of the "big picture", where you want to be, and how you are going to get there. It requires the discipline to assert the practices that will keep you on the path to your long-term goals without succumbing to practices that although productive in the short-run will eventually burn you out. At times, it requires a lot more mental toughness to keep the "goal" in your sights than it does to charge ahead full-steam with everything you've got; especially when the startup landscape is so fickle.
