"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."-Theodore Roosevelt
I just want to add something my pastor said in a sermon a few months back. This is my remembering of it so it might not be an exact quote--"God calls us to be obedient, not necessarily to be successful" Whether we succeed or fail, if we are following hard after God we are on the right path.
