What one book could pretty much give me a new, useful superpower if I follow it and put the methods inside into practice? In my life, I've come across a small handful of books that have really allowed me to learn to do some things that were previously unthinkable to me, and which I'm able to use all the time in my life. I'm most interested in a book that has actually worked to change your life, rather than one that seems like it would be good if you one day got around to following it. Thanks.
