I don't what you make of the above picture but once again you can see that the importance of wide and extensive reading really cannot be overemphasized.
Some say reading as an exercise increases knowledge, others say it broadens your horizon... well on the whole, you become invaluable to wise and knowledgeable people. You put yourself on the map.
Like I always say bury yourself in good books with every opportunity you get and never stop because you can never get enough. Remember your brain is incredibly elastic and always hungry for new and more information and will respond if you call on it to retract stored information. The only food for your brain apart from thinking is reading. So read more, let the overflow of the ocean of knowledge in books drown your ignorance and illiteracy and transform you into the optimus prime of knowledge.
