I may be a little bias. Knowledge is power only in application. One who doesn't read/listen is no better off than one who can't read/listen. Deliberately tapping into the most noteworthy thoughts in history, integrating lifetimes of lessons and decades of research. Don't take your current abilities for granted. You could wake up blind or deaf tomorrow. While we have the capability to receive wisdom the fast and easy way (easy relative to living lifetimes of experience filled with mistakes) let's gratefully and enthusiastically enjoy these gifts.
What if you could read 4x faster and comprehend more?
