"Overachievement is aimed at people who want to maximize their potential. And to do that, I insist you throw caution to the wind, ignore the pleas of parents, coaches, spouses, and bosses to be "realistic." Realistic people do not accomplish extraordinary things because the odds against success stymie them. The best performers ignore the odds. I will show you that instead of limiting themselves to what's probable, the best will pursue the heart-pounding, exciting, really big, difference-making dreams-so long as catching them might be possible."
