There's something very comforting about a well worn book.  You know the kind I'm talking about:  dog-eared pages, underlined sentences, notes to self in the margin, a cover that won't close anymore because it's been opened so much.  I have a stack of them.  Every time I feel like the world is spinning a little bit off its axis, I reach for one of these books.  They're tried, true, tested.  I know that they will deliver what I ask of them:  a little peace, a small movement back toward balance.  This is one of my favorites -- it's full of essays written by people who seem to know what they're talking about.  What are some of your well worn favorites?  I'd love to know.
