You focus so much on your failures and your weaknesses, it has a ... paralyzing effect, where you're dwelling on stuff. For example, having goals: sometimes I have lofty goals, my friends do—we all do, we all have goals. But, if you fix yourself to that goal, and you don't see anything else on the horizon—which is natural, 'cos that what it takes, we all have that in our personality ... but, sometimes, if you attach that to a goal that is out of your reach, and you continue to fail, it will just grind you into nothing. And if you dwell on that, it can end you.
