Tell a child, a husband or an employee that he is stupid or dumb at a certain thing, that he has no gift for it, and that he is doing it all wrong and you have destroyed almost every incentive to try to improve. But use the opposite technique, be liberal with encouragement; make the thing seem easy to do, let the other person know that you have faith in his ability to do it, that he has an undeveloped flair for it - and he will practice until the dawn comes in at the window in order to excel.
Dale CarnegiePractice, practice, practice in speaking before an audience will tend to remove all fear of audiences, just as practice in swimming will lead to confidence and facility in the water. You must learn to speak by speaking.
Dale CarnegieI know men and women can banish worry, fear and various kinds of illnesses, and can transform their lives by changing their thoughts. I know! I know! I know! I have seen such incredible transformations performed hundreds of times. I have seen them so often that I no longer wonder at them.
