Success in dealing with people depends on sympathetic grasp of the other person's viewpoint.

Check up each week on the progress you are making. Ask yourself what mistakes you have made, what improvement, what lessons you have learned for the future.

Is enthusiasm important in selling? Yes, genuine, heartfelt enthusiasm is one of the most potent factors of success in almost any undertaking.

George Bernard Shaw was right. He summed it all up when he said: "The secret of being miserable is to have the leisure to bother about whether you are happy or not."

It's the cheapest kind of medicine there is on this earth-and one of the best.
