The source of happiness

I think it is safe to say that all people want to be happy. People search their whole lives for happiness. What people do not realize is that happiness is not something you find, happiness is a state of being. People look for happiness in money, cars, houses, drugs, sex, and even love. These things do not create happiness, they amplify it. You must first achieve it. Happiness comes from within and until you are happy with yourself you will never truley be happy even with the greatest spouse or all of the money in the world. Stop searching for a fish on the beach.
Don't get me wrong, I am not saying that these things can't be to blame for times of unhappiness. But to determine the source of unhappiness one must first start with themself.
Now that being said I find it obsurd for someone to believe that being in love/ being loved can possibly make them happy. If you think you have to rely on someone else to be happy then you obviously don't love yourself. So instead of spending your days trying to improve yourself and love yourself you are using your time trying to improve a relationship that is destined for failure.
