“Most of us don’t have the discipline to stay focused on a single goal for five, ten, or twenty years, giving up everything to bring it off, but that’s what’s necessary to become an Olympic champion, a world class surgeon, or a Kirov ballerina. Even then, of course, it may be all in vain. You may make a single mistake that wipes out all the work. It may ruin the sweet, lovable self you were at seventeen. That old adage is true: You can do anything in life; you just can’t do everything. That’s what Bacon meant when he said a wife and children were hostages to fortune. If you put them first, you probably won’t run the three-and-a-half-minute-mile, make your first $10 million, write the great American novel, or go around the world on a motorcycle. Such goals take complete dedication.”
