Happiness is not a goal; it is a by-product.

Each of us has... all the time there is. Those years, weeks, hours, are the sands in the glass running swiftly away. To let them drift through our fingers is tragic waste. To use them to the hilt, making them count for something, is the beginning of wisdom.

Happiness is not a goal...it's a by-product of a life well lived.

Happiness is a by-product. You cannot pursue it by itself.

Since you get more joy out of giving joy to others, you should put a good deal of thought into the happiness that you are able to give.

Virtue is simply happiness, and happiness is a by-product of function. You are happy when you are functioning.
