“Happiness is not a goal...it's a by-product of a life well lived.”
“[Happiness is] a ghost, it’s a shadow. You can’t really chase it. It’s a by-product, a very pleasant side effect to a life lived well.”
“If you want to live a happy life, tie it to a goal, not to people or things.”
“The purpose of life is not to be happy—but to matter, to be productive, to be useful, to have it make some difference that you lived at all.”
“Happy people learn that happiness, like sweat, is a by-product of activity. You can only achieve happiness if you are too busy living your life to notice whether you are happy or not.”
“More important than success is the individual who strives towards his goal. It is the effort which counts. The goal is just a finish line - it accomplishes there and its happiness short lived.”
