Why prove to a man he is wrong? Is that going to make him like you? Why not let him save face? He didn't ask for your opinion. He didn't want it. Why argue with him? You can't win an argument, because if you lose, you lose it; and if you win it, you lose it. Why? You will feel fine. But what about him? You have made him feel inferior, you hurt his pride, insult his intelligence, his judgment, and his self-respect, and he'll resent your triumph. That will make him strike back, but it will never make him want to change his mind. A man convinced against his will is of the same opinion still.

I want you to think of your life as an hourglass. You know there are thousands of grains of sand in the top of the hourglass; and they all pass slowly and evenly through the narrow neck in the middle. Nothing you or I could do would make more than one grain of sand pass through this narrow neck without impairing the hourglass. You and I and everyone else are like this hourglass.

Excitement radiates through your eyes, your face, your voice, your soul, and your whole personality.

A good deed, "said the prophet Mohammed, "is one that brings a smile of joy to the face of another." Why will doing a good deed every day produce such astounding efforts on the doer? Because trying to please others will cause us to stop thinking of ourselves: the very thing that produces worry and fear and melancholia.
