 You are the only species on the planet that is able to grow and get bigger and bigger all of your life. There are no giraffes that are watering hole in South Africa tonight, having a conversation about lifting their game, about being better giraffes, because they don't have self-awareness. They're not aware that they can be better giraffes than they have been in the first part of their lives. Only human beings are capable of doing that, and yet the truth is most human beings don't read a book when they don't have to read one anymore.
