I recommend anybody go to a bookstore, go down the self-help or new-age section, and just walk those aisles. See what book jumps out at you; there's a good chance it's a book you need in your life. That's basically how I find the books that I read.
I read true crime books, and I read when people do case studies of stuff. I'm into books like that. Case studies or forensics or murder - all that good stuff.
I read a book recently by a psychiatrist who was able to interview a few serial killers and she had a thesis on how you could figure these people out. And she thinks that there are things that could tell you whether someone has the potential to do that.
People are not in good shape to where they have to question their own belief system because of a book or a story somebody wrote, or a SLAYER song.
