You are no greater than the friends you keep, the books you read, the heroes you admire, and the obstacles you overcome.
Knowledge gives you the world, intelligence gives you the sky, understanding gives you the stars, but wisdom gives you the universe.
In my youth I had three teachers: friends, enemies, and books. In my adulthood I had three professors: God, nature, and life.
A book is the only vehicle that can take you around the world in one hour.
A few hours spent reading a book is better than a lifetime of ignorance.
Education costs an arm and a leg, but ignorance costs you your mind and your soul.
