I often hear people say,
you should not do it for the money
or the famous quote money doesn't make you happy.
To which I think to myself well yeah, if you already have money,
then getting more money does not necessarily make you happy or happier.
But when you're piss poor, or in debt, and need that extra money to pay for your medical bills. Then money will definitely make you happy. I believe this goes for the majority of people.
So when someone says money doesn't make you happy. I think it is a really shallow statement unless you're telling that to someone who already has enough money or is filthy rich.
