Reading a book is among the most high-leverage activities on earth. For an investment more or less equivalent to the length of a single workday (and a few dollars), you can gain access to what the smartest people have already figured out. Reading, that is, reading to really understand, delivers residual results by any estimate. Unfortunately, very few people take advantage of this. The typical American reads (or partially reads) only four books a year. More than a quarter of Americans don’t read books at all. And this trend is worsening.
