(1888-1955) American Writer, Lecturer [Dale Carnegie at Amazon]
Happiness doesn’t depend on any external conditions, it is governed by our mental attitude.
It isn’t what you have, or who you are, or where you are, or what you are doing that makes you happy or unhappy. It is what you think about.
Develop success from failures. Discouragement and failure are two of the surest stepping stones to success.
Success is getting what you want. Happiness is wanting what you get.
