A wizard from the start, Thomas Edison had a thirst for knowledge, taste for mischief, and hunger for discovery--but 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 and did 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.
