His family was so poor that Jack had to leave school to make money at an early age. As a result, he had little education as a child. He worked hard in many different jobs--- working as a paper boy, a sailor, and a miller. Though he had to work long hours at these jobs, London spent all his free time on books, especially those travel and adventure books borrowed from the library. He travelled to Japan and Korea in 1893. These trips made London decide to educate himself and change his life. He returned to school, quickly completed high school and entered the University of California. After only one term, however, London gave up his studies and travelled to Alaska in 1897 in search of gold, but he failed as a gold miner. Though unsuccessful, the trip to Alaska provided ideas for his career as a writer. Once back in California, London decided to work as a writer. He bought a typewriter and worked up to fifteen hours a day, changing his Alaskan adventures into short stories and novels. In 1903, he became famous all over the country after he published the popular novel The Call of the Wild. He soon became the highest paid writer in the US. During his career, he wrote more than fifty books and got more than a million dollars. Several of his novels, including The Call of the Wild (1903), The Sea Wolf (1904), The White Fang (1906), have become American most famous novels. People can always get encouragement and ideas about life from his works. To Build a Fire, for example, tells the story of a man who fought against the extreme cold to live through the Alaskan winter.Jack London was a great writer in the history of literature.
