Be a balanced optimist. Nobody is suggesting that you become an oblivious Pollyanna, pretending that nothing bad can or ever will happen. Doing so can lead to poor decisions and invites people to take advantage of you. Instead, be a rational optimist who takes the good with the bad, in hopes of the good ultimately outweighing the bad, and with the understanding that being pessimistic about everything accomplishes nothing. Prepare for the worst but hope for the best - the former makes you sensible, and the latter makes you an optimist.

Remember that other people may be totally wrong. But they don't think so. Don't condemn them. Any fool can do that. Try to understand them. Only wise, tolerant, exceptional people even try to do that.

Winning friends begins with friendliness.

The difference between appreciation and flattery? That is simple. One is sincere and the other insincere. One comes from the heart out; the other from the teeth out. One is unselfish; the other selfish. One is universally admired; the other universally condemned.

Don't fuss about trifles. Don't permit little things-the mere termites of life-to ruin your happiness.

Let's fight for our happiness by following a daily program of cheerful and constructive thinking.

Names are the sweetest and most important sound in any language.
