I think what you said is quite reasonable，very smart. But this is easy to say though. It can, as almost anything, be harder to do.
Sadly，even though i know this，but i think i am one of the greedy people eventually.
Saying without doing is indeed very easy, because everyone is able to make words but not everyone is able to do it, because greediness is a trait that has been embedded in humans so it is a little more difficult to get rid of quickly.
