Unconventional wisdom from the book, "If It Ain't Broke, Break It," authors Robert J. Kriegel and Louis Parker:
"We don't have a clue as to what people's limits are. All the tests, stopwatches, and finish lines in the world can't measure human potential. When someone is pursuing their dreams, they'll go far beyond what seems to be their limitations. The potential that exists within us is limitless and largely untapped. When you think of limits, you create them."
