Quote from : How to Win Friends and Influence People Book

I don't blame you one iota for feeling as you do. If I were you I would undoubtedly feel just as you do."(...) You can say that and be 100 percent sincere, because if you were the other person you, of course, would feel just as he does (...) Suppose you had inherited the same body and temperament and mind (...) Suppose you had had his environment and experiences. You would then be precisely what he was - and where 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.
