* A day of worry is more exhausting than a day of work.
* Any fool can criticize, complain, condemn, and most fools do.
* Don’t mind criticism. If it is untrue, disregard it. If it is unfair, keep from irritation. It if is ignorant, smile. If it is justified, learn from it.
* I complained because I had no shoes until I met a man who had no feet.
