"It is not the critic who counts: not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself for a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat."
Teddy Roosevelt, speaking at the Sorbonne in Paris, April 23, 1910
This is one of my favorite quotes. It really sums up the spirit of the entrepreneur. At some point, they had to take the "entrepreneurial leap" and take a chance on themselves. That is a decision that very few regret.
