I shall never forget how I was roused one night by the groans of a fellow prisoner, who threw himself about in his sleep, obviously having a horrible nightmare. Since I had always been especially sorry for people who suffered from fearful dreams or deliria, I wanted to wake the poor man. Suddenly I drew back the hand which was ready to shake him, frightened at the thing I was about to do. At that moment I became intensely conscious of the fact that no dream, no matter how horrible, could be as bad as the reality of the camp which surrounded us, and to which I was about to recall him.
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.
The great difference between those who succeed and those who fail does not consist in the amount of work done by each but in the amount of intelligent work. Many of those who fail most ignominiously do enough to achieve grand success but they labor haphazardly at whatever they are assigned, building up with one hand to tear down with the other. They do not grasp circumstances and change them into opportunities. They have no faculty for turning honest defeats into telling victories. With ability enough and ample time, the major ingredients of success, they are forever throwing back and forth an empty shuttle and the real web of their life is never woven.
The weakest living creature, by concentrating his powers on a single object, can accomplish good results while the strongest, by dispersing his effort over many chores, may fail to accomplish anything. Drops of water, by continually falling, hone their passage through the hardest of rocks but the hasty torrent rushes over it with hideous uproar and leaves no trace behind.
