Rogers on discipline

Most of us don't have the discipline to stay focused on n 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 n Kirov ballerina. Even then, of course, it may be all in vain.
You may make n 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 S10 million, write the great American
novel, or go around the world on n motorcycle. Such goals take
complete dedication."- Jim Rogers
