A bit wiser, what would a Holden Caufield over-50 warn us against? Of course, it wouldn't be to avoid the phony. Caufield would by then understand the layers of subterfuge we human beings pile on, just to survive.
Likely what he would tell us to be most wary of were those who told us how to be successful. That kind of know-how doesn't pass from person to person. It's too idiosyncratic. The way to be successful is to find that out on our own. I started to do just that in 2003 [Download Geezerguts.] It's worked out. Eight years later, my success is my way. Unlike Jack Malone, FBI team leader on "Without a Trace," it doesn't cost me too much either any more.
