As far as I have understood INFJs tend to be idealistic. When I talked to my dad of my dreams of helping people in the world and that I wouldn't mind putting myself into harm's way(ie the risk of getting killed) to help other people he said: "You may be idealistic when you're young but at my age you'll be content with the things you have achieved". I thought it was silly but I let it go. Yesterday when speaking to my friend (she's an ENFJ if it would matter) she told me that she instantly thought of me when she read this in The Catcher in the Rye" “The mark of the immature man is that he wants to die nobly for a cause, while the mark of a mature man is that he wants to live humbly for one” I was pretty baffled because I could somehow understand what my Dad said. The question is though, are we more prone to let our causes fade away the older we get alternatively approach them more realistically? Or are we still die hard idealists?
