Quality or worth of a life is measured by its clear definition and goal.
The best of life is attained by those who are living for a cause and not for a cost to earn.
You may earn much by thinking cost but you will certainly yearn for more by pursuit of a cause.
What you earn will limit you but what you but what you yearn for will stretch you and provide for you far more than what you earn.
Define your cause and stick to it – That is exactly what you are created for.
Your cause is the fountain of your joy and fulfillment.
