Les Giblin quotes:

If you are not using your smile, you're like someone with a million dollars in the bank and no checkbook.

You can't make the other fellow feel important in your presence if you secretly feel that he is a nobody

There is a hunger in every human being for approval.

What counts is a way to get along with people that will bring us personal satisfaction and, at the same time, not trample upon the egos of those we deal with.
