In case of doubt, do a little more than you have to.
What I focus on in life is what I get. And if I concentrate on how bad I am or how wrong I am or how inadequate I am, if I concentrate on what I can't do and how there's not enough time in which to do it, isn't that what I get every time? And when I think about how powerful I am, and when I think about what I have left to contribute, and when I think about the difference I can make on this planet, then that's what I get. You see, I recognize that it's not what happens to you; it's what you do about it.
