Confusion is the main cause of worry

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." The river changes every second; and so does the man who stepped in it. Life is a ceaseless change. The only certainty is today. 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?

If we rail and kick against it and grow bitter, we won't change the inevitable; but we will change ourselves. I know. I have tried it. I once refused to accept an inevitable situation with which I was confronted. I played the fool and railed against it, and rebelled. I turned my nights into hells of insomnia. I brought upon myself everything I didn't want. Finally, after a year of self-torture, I had to accept what I knew from the outset I couldn't possible alter.

Happiness is largely an attitude of mind, of viewing life from the right angle.
