We may find it convenient to live with the illusion that circumstances or other people are responsible for the quality of our lives, but the reality is that we are responsible-response-able-for our choices.
Stephen CoveyPeople 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.
