Money. Can it buy happiness?

Money is a huge part of our lives and there really isnt anyone who can denie it. I believe money can buy happiness, but not in the sense of you go buy a car and you feel joy and happiness forever. I think a lot of your happiness has to come from inside yourself. I heard a study say that money can buy happiness in the sense of if you go buy something for someone or give a bum money or just give someone else money it can buy happiness and joy. As I look back I notice that when I give gifts I feel so good about myself and I feel happy. I almost like giving more than reviving things. When you give a present to someone you just feel joyful and happy because your saying "hey" I gave that person food or just straight up money and they got happy. But in the other sense that if you go buy a new car purse I really dont agree. Ya you get happy when you go buy something but I dont think it last that long. I think that money def. makes things easier which brings happiness and it also allows you to do the activities you love which also makes you happy. I would have to say that there isnt a human on the earth that doesnt get any joy from giving.
