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.

Cash can buy, but it takes enthusiasm to sell.

Instead of condemning people, let's try to understand them. Let's try to figure out why they do what they do. That's a lot more profitable and intriguing than criticism; and it breeds sympathy, tolerance and kindness.

If you want others to like you, if you want to develop real friendships, if you want to help others at the same time as you help yourself, keep this principle in mind: Become genuinely interested in other people.

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.

criticism is dangerous, because it wounds a person's precious pride, hurt his sense of importace and arouse resentment.

Life truly is a boomerang. What you give, you get.
