"The failure to read good books both enfeebles the vision and strengthens our most fatal tendency --the belief that the here and now is all there is."
Allan Bloom actually had a lot to say about reading and books. Most of what he said was pretty great too. Go read a great book because you wouldn't want your vision enfeebled. Also, so you can realize that the past has significance for all of us.
If you aren't reading good books, you are missing out on so many of the great lessons they offer. Learning from mistakes is much easier when they happen in a story.
