Dear Robert Greene: your book deserves better graphic design as other people already pointed out. Moving on content: thank you note for describing and summarizing years of social psychology studies on human behavior except Envy. Just this chapter deserves a milestone in history. Even the billionaire Munger noticed years ago (1995) that Envy had been notably absent as subject in psychology and sociology- I agree. I research about it and nothing comes out, well Joseph story in the Bible, but not academically. I wait and wait for this book and finally I got it. Thanks again Dear Robert.
