Many of those who get what they want in terms of money or fame are depressed, because they have achieved what they wanted and it has not made them happy. They cannot continue a search which has already achieved the goal. This is why you see so many who have addictions, because they try to numb the depression and pain. What they are truly looking for, what we are all truly looking for, is God's Love. Being in communion with Him is what gives us joy. Regardless of the outer circumstances --- whether you are rich or poor, old or young, the president of the U.S. versus a homeless person --- you already have everything you need to be joyful. There is no search, because joy is intrinsic. Happiness in the world's terms can be defined as something "outside" of you which temporarily gets you excited. Joy does not depend on anything outside of you that is temporary and fleeting. The fame, the money, the new house, can all go away tomorrow. But joy is your birthright, and your relationship with Him, which gives you joy, is eternal.
