With money very tight for his family, Cosby started shining shoes to help out when he was 9 years old. He also later found a job at a supermarket. Despite their hardships, Cosby's mother stressed the value of education and learning. She often read to Bill and his brothers, including the works by Mark Twain. A gifted storyteller himself, Cosby learned early on that humor could be a way to make friends and to get what he wanted. Cosby excelled at making things up. As one of his teachers once noted, "William should become either a lawyer or an actor because he lies so well.''
