As i read them with interest, i recall an equation my father used to tell me when i was a kid. Anytime I complained about how unhappy i was because I did not have everything that my friends had, he used to smile and tell me his formula for happiness and contentment.
"Happiness = what we have /what we desire. To be happy, the answer to this equation should always be more than '1'. There is no limit to what you can desire but there is a limit to what you have. So now it is upto you. You can choose to be either happy or unhappy"
Scientists today have worked out a far more complex formula for happiness . However to me, that piece of wisdom that i received from my father will always remain most precious and everytime i lose my way, i am sure it will lead me back onto the path of happiness.
