Remember that other people may be totally wrong. But they don't think so. Don't condemn them. Any fool can do that. Try to understand them. Only wise, tolerant, exceptional people even try to do that.
Dale CarnegieIf you got it, ask yourself why and try to repeat the action. If you failed, ask yourself why and try to learn from the experience.
Dale CarnegieA ship in the harbor is safe, but that is not what ships are built for. Intelligence is like underwear, everyone has it, but you don't have to show it off. The expression a woman wears on her face is more important than the clothes she wears on her back.
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.
