Happiness doesn't depend on any external conditions, it is governed by our mental attitude.
Dale CarnegieAn effective speaker knows that the success or failure of his talk is not for him to decide - it will be decided in the minds and hearts of his hearers.
Dale CarnegieNothing else so inspires and heartens people as words of appreciation. You and I may soon forger the words of encouragement and appreciation that we utter now, but the person to whom we have spoken them may treasure them and repeat them to themselves over a lifetime
Dale CarnegieI want you to think of your life as an hourglass. You know there are thousands of grains of sand in the top of the hourglass; and they all pass slowly and evenly through the narrow neck in the middle. Nothing you or I could do would make more than one grain of sand pass through this narrow neck without impairing the hourglass. You and I and everyone else are like this hourglass.
