Thinking about opportunity

Yesterday I started reading the latest Gail Bowen, Joanne Kilbourn series book, "A Darkness of the Heart".  There was a description of a well respected man who had recently died, "he lived with his arms wide open, ready to embrace new experiences, new people, new ideas."  This is contrasted to someone else who "...grew up with inner walls, within inner walls."  Is this not very much like the discussions we've been having about opening ourselves up to new opportunities?  Just those two sentences gave me a lot to think about.  Have either of you read any of her books?  I've read a few, but not all, and have enjoyed them immensely.  Such a change to read something based within Canadian political systems and locations, but a good mystery, none the less.
