Sell a stock only when you have found a new stock that is a 50% better bargain than the one that you hold.

Bull markets are born on pessimism, grown on skepticism, mature on optimism and die on euphoria. The time of maximum pessimism is the best time to buy, and the time of maximum optimism is the best time to sell.

Self-improvement comes mainly from trying to help others.

Many of us understand giving, but some of us may still be confused about the meaning of forgiveness. Some people may go through life in a groveling mode, mistakenly believing they have to receive forgiveness from others. Forgiveness offers more than a reprieve granted to us by another person. True forgiveness is a process of giving up the false for the true and allows us to rid our thinking of rigid ideas. We can develop the flexibility to change our mind and our behavior patterns to higher and greater expressions and find new avenues to freedom.

I served for 42 years on the board of trustees of the largest Presbyterian seminary, Princeton Theological Seminary, and we had brilliant people - teachers and students both-but they did not come up with many new concepts. They weren't invited to come up with new concepts. Anybody who had come up with a new concept would have been under suspicion for being out of step with the tradition or out of step with the teachings of the church.

Your mission in life is to have a "why" to live for, to use your best qualities in the service of the kind of world in which you would like to live. That is your purpose. This is what life expects of you. And when you live according to your purpose, setting goals that support it, you may find the pieces of your life drawn together into a strong internal whole. Then, no matter how difficult life's experiences may prove to be, you can be able to endure and even prevail.

There is a distinction between failing and being a failure. Few things are learned in life without failing at least once. Did you learn to roller skate without falling a few times? Did you learn to ride a bike without losing your balance? Chances are you didn't. You may have wanted to do those things so intensely that you quickly put unsuccessful attempts behind you and kept trying. Soon you acquired the skill to do the thing you wanted. Even though in the process of learning you may have failed many times, you were not a failure. "Failing" simply became an open door to try again.
