Why would you want a LOT of money when all you really need is enough to not have to worry about putting food on the table or how to pay your bills this month?

IMHO it's much more important to find some sort of occupation that not only makes money, but that you actually enjoy doing long term, otherwise you're just going to get burnt out. And I can tell you from my own experience that no amount of money is worth that.

Also, it doesn't matter WHAT you do, there's always going to be someone criticizing or hating on you, no matter how good you are. In fact, the better you are, the more hate you'll get. But that doesn't make it immoral.
