I am a simple reader -- I read books requiring limited thought with large print.
Grisham novels therefore are protoypical reading for Neurotic Guy. Brethren, as previously mentioned, was good, but my personal favorite is The Rainmaker - struck me in all the right ways and met my definition of a good book: disappointed when it ended. Also enjoyed The Client. I find Grisham novels work for me even if I've already seen the movie.
I typically avoid self-help books since I believe myself to be beyond hope and therefore am depressed by attempts to cheer me up. However, years back, I enjoyed 'The Erroneous Zones' which pointed out many of the negative thinking patterns that I still employ to this day.
Non-fiction favorite: David Mcullough -- Please read '1776' - just great. And, 'John Adams'. Amazing work.
I was also fascinated by 'The Endurance' which pieced together a truly unbelievable voyage to Antarctica through the actual diaries of crew. Amazing.
Last note. I tried Cormac McCarthy years ago with his book "The Orchard Keeper'. Could not get through it. Reminded me of Faulkner who I could also not tolerate. It's probably me. But, based on recommendations in this thread, perhaps I'll give him another try.
