“Our fatigue is often caused not by work, but by worry, frustration and resentment.”

If you are wrong, admit it quickly and emphatically.

The way to defeat fear: decide on a course of conduct and follow it. Keep so busy and work so hard that you forget about being afraid.

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.

Learning is an active process. We learn by doing.. Only knowledge that is used sticks in your mind.

If you must make a mistake, make a new one each time.

If you are not in the process of becoming the person you want to be, you are automatically engaged in becoming the person you don’t want to be.

The successful man will profit from his mistakes and try again in a different way.

Abilities wither under criticism; they blossom under encouragement.

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.

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.

Inaction breeds doubt and fear. Action breeds confidence and courage.

Perhaps you will forget tomorrow the kind words you say today, but the recipient may cherish them over a lifetime.

Use encouragement. Make the fault seem easy to correct.

Try honest to see things from the other person’s point of view.

The most important thing in life is not simply to capitalize on your gains. Any fool can do that. The important thing is to profit from your losses. That requires intelligence, and makes the difference between a man of sense and a fool.

Success in dealing with people depends on sympathetic grasp of the other person’s viewpoint.
