In the end, if you were not happy before you were rich, it's unlikely you will be happy when you are (rich).
My two cents.
Money can't buy you happiness they say. But it can buy so many nice things (including lambos, hookers and blow) that can make your life at least a tiny bit happier...

I wasn't happy a good time of my past life, but i well could enjoy
things.
I think many people confuse happiness and joy.
