Something very interesting happened to me. Not too long after I started reading personal development books and articles, my dad was moving to a new house and cleaning out his attic. I knew there would be some books in there so I went over to his house and looked through them.
I had found myself a copy of Think and Grow Rich that hadn't been touched in 19 years. And I had no idea that it was such a popular book at the time. I don't even remember how I used to think before I started reading books like that.
