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.
Stephen CoveyWhen life does not go our way or we inadvertently make a mistake, it is so easy to make excuses, place blame on others, or argue that circumstances were against us. But we only progress in life to the extent that we take responsibility for our actions and attitudes, and put forth the initiative necessary to create our own circumstances.
