When we hate our enemies, we are giving them power over us: power over our sleep, our appetites, our blood pressure, our health and our happiness. Our enemies would dance with joy if only they knew how they were worrying us, lacerating us, and getting even with us! Our hate is not hurting them at al, but our hate is turning our days and nights into a hellish turmoil.

Dealing with people is probably the biggest problem you face, especially if you are in business. Yes, and that is also true if you are a housewife, architect or engineer.

Remember that the people you are talking to are a hundred times more interested in themselves and their wants and problems than they are in you and your problems.

It isn't what you have, or who you are, or where you are, or what you are doing that makes you happy or unhappy. It is what you think about.

Flattery is telling the other person precisely what he thinks about himself.

If we rail and kick against it and grow bitter, we won't change the inevitable; but we will change ourselves. I know. I have tried it. I once refused to accept an inevitable situation with which I was confronted. I played the fool and railed against it, and rebelled. I turned my nights into hells of insomnia. I brought upon myself everything I didn't want. Finally, after a year of self-torture, I had to accept what I knew from the outset I couldn't possible alter.

Your smile brightens the lives of all who see it. To someone who has seen a dozen people frown, scowl or turn their faces away, your smile is like the sun breaking through the clouds.
