There is no shame in re-reading, though I have friends who are firmly against it. I don’t have many books I reread, but I have authors I reread: Tolkien, William Gibson, Steven Levy among others. We shouldn’t ignore books that are new to us, but we should return eagerly to those books we love, just as we return to the people and the places we love, because they have helped make us who we are, and sometimes we need to be reminded of that.
