I think it's just recognizing that who you are is not any of the stuff that you have. It's not any of the things of the ego. Coming to that awareness is a very hard thing for most people to do - but that's an excuse. If you tell yourself it's too hard, then you won't take it on. But right now, for most people, it's almost an impossibility to do so, because they're so attached to "I am what I have"; "I am what I do"; "I am what my reputation is"; or "I am all of this material stuff."
