“Success is getting what you want..Happiness is wanting what you get.”

“Everybody in the world is seeking happinessand there is one sure way to find it. That is by controlling your thoughts. Happiness doesn't depend on outward conditions. It depends on inner conditions.”

“Remember, happiness doesn't depend upon who you are or what you have, it depends solely upon what you think.”

“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 it.”

“Don't be afraid of enemies who attack you. Be afraid of the friends who flatter you.”

“Are you bored with life? Then throw yourself into some work you believe in with all your heart, live for it, die for it, and you will find happiness that you had thought could never be yours.”

“Spring work is going on with joyful enthusiasm.”

“Enthusiasm is a supernatural serenity.”

“It's faith in something and enthusiasm for something that makes a life worth living.”
