Quotes from the same author

Lose/Win people bury a lot of feelings. And unexpressed feelings come forth later in uglier ways. Psychosomatic illnesses often are the reincarnation of cumulative resentment, deep disappointment and disillusionment repressed by the Lose/Win mentality. Disproportionate rage or anger, overreaction to minor provocation, and cynicism are other embodiments of suppressed emotion. People who are constantly repressing, not transcending feelings toward a higher meaning find that it affects the quality of their relationships with others.
People with a scarcity mentality tend to see everything in terms of win-lose. There is only so much; and if someone else has it, that means there will be less for me. The more principle-centered we become, the more we develop an abundance mentality, the more we are genuinely happy for the successes, well-being, achievements, recognition, and good fortune of other people. We believe their success adds to...rather than detracts from...our lives.
Start small, make a promise and keep it. Then, make larger promises and keep them. Eventually, your honor will become greater than your moods or your circumstances, which includes your medical condition and other people's stereotypic observations. Once you overcome this comparison based mentality, your confidence will soar.
We are not animals. We are not a product of what has happened to us in our past. We have the power of choice.
Instead, I have an abundance mentality: When people are genuinely happy at the successes of others, the pie gets larger.
