People like to hypothesize what they would do if they suddenly got rich or won the lottery. Aside from "buy my momma a new car" and "get a big house", people usually indicate they'd donate something to charity.
That's a great thought, but I guess I tend to think that a person's financial habits are molded when they have less. Instead of thinking, "When I cross XXX financial goal, then I'll finally have enough to be generous," maybe a better thought is, "There are people in the world living with much, much less than I. What can I afford to give right now?"
