The following comes from a book I've just started to read (and enjoying it greatly) by Ken Rolf titled "Your Greatest Victory:"
“I can honestly say, from the bottom of my heart, I have never had a crisis in my life or a setback thatʼs not made me stronger, and itʼs turned out to be a positive thing in my life -- if I reacted positively to it. And many times I feel that the adversity and the setbacks that you experience are preparing you for something bigger and better, so when you get in that situation, or even a tougher one in the future, youʼll be able to handle it.”
—Lou Holtz
