A wizard from the start, Thomas Edison had a thirst for knowledge, taste for mischief, and hunger for discoverybut his success was made possible by his boundless energy. At age fourteen he coined his personal motto: "The More to do, the more to be done," and then went out anddid: picking up skills and knowledge at every turn. When learning about things that existed wasn't enough, he dreamed up new inventions to improve the world. From humble beginnings as a farmer's son, selling newspapers on trains and reading through public libraries shelf by shelf, Tom began his inventing career as a boy and became a legend as a man.
