The average man takes life as a trouble. He is in a chronic state of irritation at the whole performance. He does not learn to differentiate between troubles and difficulties, usually, until some real trouble bowls him over. He fusses about pin-pricks until a mule kicks him. Then he learns the difference.
Do you know how much you can learn from a mere pair of high-heels? If you don't fall, you'll learn a bit, but If you do fall, you'll learn everything. If you become successful, you'll learn a bit, but if you fail, you'll get to learn everything. Success is the dumbest teacher, not the other way around
