Are you familiar with the saying "Happiness is an inside job"?
This is not true. Happiness is an outside job, that is, searching outside yourself you can find happiness but inherent in the finding of happiness is the eventual unhappiness. It's inevitable when searching for fulfillment outside of you.
Joy, however, is an inside job. Joy is not contingent on any person, circumstance, situation etc. Joy is. Seek for it inside, and you shall find.
