The best measure for success is not on how much one earns but on how fulfilled one is on what he or she earns
That’s to say that one can earn so big and yet dies unfulfilled.
A man who earns millions without appreciating it is not satisfied and can never be fulfilled. Having in mind that being satisfied with what you earn does not means you should stop earning more but shows that you have decided to make yourself happy for where you are and happiness in turn is the key to fulfilment.
Therefore, be happy with your income and this will give you peace of mind that leads to good reasoning which produces more success without harm.
