I heard about a woman, who was in a car that had stalled at the intersection. Try as she might, she could not get the car started. Behind her was a man, who insisted on honking his horn every few seconds.
Finally, the woman got out of her car, walked calmly back to the man's car, looked into the window, and said, "I'm having trouble getting my car started. Why don't you go up there and see if you can fix it, and I'll sit in your car and honk the horn at you?"
It's a lot easier to honk the horn than to fix the car.
It is a lot easier to criticize leaders than to be one.
