“I saw what a mess a lot of people could make of their lives when they're smitten. Some of them go temporarily insane. They find a person who they think holds the key to their happiness-the only key to their happiness... My work has always been my greatest happiness”

“The key to happiness? Find someone who would rather you be happy than themselves and then you treat them the same way. That way, no matter what, you are both trying to insure the OTHER person's happiness and in turn, yours is undeniable.”

“If getting is the key to your happiness your key will open few doors. If giving is the key to your happiness you will find few doors locked.”

“Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.”

“When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down ‘happy’. They told me I didn’t understand the assignment, and I told them they didn’t understand life.”

“I had always been taught that the pursuit of happiness was my natural (even national) birthright. It is the emotional trademark of my culture to seek happiness. Not just any kind of happiness, either, but profound happiness, even soaring happiness. And what could possibly bring a person more soaring happiness than romantic love.”
