For Sparky, school was all but impossible. He failed every subject in the eighth grade. He flunked physics in high school, getting a grade of zero. Sparky also flunked Latin, algebra and English. He didn't do much better in sports. Although he did manage to make the school's golf team, he promptly lost the only important match of the season. There was a consolation(安慰) match; he lost that, too.

Throughout his youth Sparky was awkward socially. He was not actually disliked by the other students; no one cared that much. He was astonished if a classmate ever said hello to him outside of school hours. There's no way to tell how he might have done at dating. Sparky never once asked a girl to go out in high school. He was too afraid of being turned down.

Sparky was a loser. He, his classmates...everyone knew it. So he rolled with it. Sparky had made up his mind early in life that if things were meant to work out, they would. Otherwise he would content himself with what appeared to be his inevitable mediocrity(平凡).

However, one thing was important to Sparky - drawing. He was proud of his artwork. Of course, no one else appreciated it. In his senior year of high school, he submitted some cartoons to the editors of the Yearbook. Although the cartoons were turned down., Sparky was so convinced of his ability that he decided to become an artist.

After completing high school, he wrote a letter to Walt Disney Studios. He was told to send some samples of his artwork, and the subject for a cartoon was suggested. Sparky spent a great deal of time o it. Finally, the reply came from Disney Studios. He had been rejected once again. Anther loss for the loser.

So Sparky decided to write his own autobiography(自传) in cartoons. He described his childhood - a little boy loser and chronic underachiever. The cartoon character would soon become famous worldwide. For Sparky, the boy who had such a lack of success in school and whose work was rejected again and again, was Charles Schultz. He created the Peanuts comic strip(连环漫画) and the little cartoon character whose kite would never fly and who never succeeded in kicking a football--Charlie Brown.
