If you've read one of my books, thanks. I write them to be read, so without you, it would be a pointless exercise.
I'm asking a favor: Would you give your copy (or lend, I'm fine either way) of Linchpin away?
Go find someone you care about, hand them the book and insist they read it. I'd consider that a gift of the first order, and I hope they will too.
In fact, don't just do it with Linchpin, do it with all the books that have changed you, regardless of author or age. They're not earning interest unless people are reading them. Ideas that spread, win.
