I realize now that people are not thinking about you and me or caring what is said about us. They are thinking about themselves-before breakfast, after breakfast, and right on until ten minutes past midnight. They would be a thousand times more concerned about a slight headache of their own than they would about the news of your death or mine.
Dale CarnegieIf you increase your success by even a mere 10 percent, you have become 10 percent more effective as a leader than you were before.
Dale CarnegieDon't fuss about trifles. Don't permit little things-the mere termites of life-to ruin your happiness.
