Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.
Happiness is not a reward – it is consequence. Suffering is not a punishment – it is a result.
— Robert Green Ingersoll
You don’t need anyone else’s permission to be happy. Your life is magnificent not because someone says it is, but because you choose to see it as such.
— Ralph Marston
In about the same degree as you are helpful, you will be happy.
— Karl Reiland
