Ginger,
Great topic!!
I've always been a big reader ever since I was little. However my library didn't include books that would help me grow as a person until just recently. It since has grown quite a bit and you'd rarely find a novel among my shelves these days.
Of course your top two are part of my library as well

I'd like to add some of my favorites
"The Slight Edge" by Jeff Olson and
"The Go Giver" and
"Go-Givers Sell More" by Bob Burg and John David Mann.
Readers indeed are Leaders!!
