Make a man laugh a good hearty laugh, and you've paved the way for friendship. When a man laughs with you, he, to some extent, likes you.

You can make more friends in two months by becoming interested in other people than you can in two years by trying to get other people interested in you.

When we hate our enemies, we are giving them power over us: power over our sleep, our appetites, our blood pressure, our health and our happiness. Our enemies would dance with joy if only they knew how they were worrying us, lacerating us, and getting even with us! Our hate is not hurting them at al, but our hate is turning our days and nights into a hellish turmoil.

Your purpose is to make your audience see what you saw, hear what you heard, feel what you felt.

Praise is like sunlight to the warm human spirit; we cannot flower and grow without it. And yet, while most of us are only too ready to apply to others the cold wind of criticism, we are somehow reluctant to give our fellow the warm sunshine of praise.

Act enthusiastic and you will be enthusiastic.

It isn't work that makes you tired, it's your mental attitude.
