To me, the definition of focus is knowing exactly where you want to be today, next week, next month, next year, then never deviating from your plan. Once you can see, touch and feel your objective, all you have to do is pull back and put all your strength behind it, and you'll hit your target every time.
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.
