“A good deed, "said the prophet Mohammed, "is one that brings a smile of joy to the face of another."Why will doing a good deed every day produce such astounding efforts on the doer?Because trying to please others will cause us to stop thinking of ourselves: the verything that produces worry and fear and melancholia.”

“One reason why birds and horses are not unhappy is because they are not trying to impress other birds and horses.”

“confusion is the main cause of worry”

“Our fatigue is often caused not by work, but by worry, frustration and resentment.”

“You are going to survive. And good things are going to start to happen again. And one day you are going to look back and this will not even be such a bad thing”

“Let's never try to get even with our enemies, because if we do we will hurtourselves far more than we hurt them. Let's do as General Eisenhower does: let's neverwaste a minute thinking about people we don't like.”

“Five hundred years before Christ was born, the Greek philosopher Heraclitus told his students that "everything changes except the law of change". He said: "You cannot step in the same river twice."

Why mar the beauty of living today by trying to solve the problems of a future that is shrouded in ceaseless change and uncertainty-a future that no one can possibly foretell?”
