Learning is an active process. We learn by doing.. Only knowledge that is used sticks in your mind.
Dale CarnegieThere is one all-important law of human conduct. If we obey that law, we shall almost never get into trouble. In fact, that law, if obeyed, will bring us countless friends and constant happiness. But the very instant we break the law, we shall get into endless trouble. The law is this: Always make the other person feel important.
Dale CarnegieSuppose you had inherited the same body and temperament and mind that Al Capone had. Suppose you had had his environment and experiences. You would then be precisely what he was. . . . For it is those things - and only those things - that made him what he was. . . . You deserve very little credit for being what you are - and remember, the people who come to you irritated, bigoted, unreasoning, deserve very little discredit for being what they are.
