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.

For most of human history, the dominant concerns about energy have centered on the benefit side. Inadequacy of energy resources of the technologies for harvesting, converting, and distributing those resources has meant insufficient energy benefits to human beings and hence inconvenience, and constraints on its growth. The 1970’s, then, represented an turning point. Energy was seen to be getting costlier in all respects. It began to be believable that excessive energy costs could pose threats on a par with those of insufficient supply. It also became possible to think that expanding some forms of energy supply could create costs exceeding the benefits.

阅读下面一段文字：

“傍晚，我靠着逐渐黯淡的最后的阳光的指引，走过十八年前的故居。这条街、这个建筑物开始在我的眼前隐藏起来，像在躲避一个久别的旧友。但是它们的改变了的面貌于我还是十分亲切。我认识它们，就像认识我自己。还是那样宽的街，宽的房屋。巍峨的门墙代替了太平缸和石狮子，那一对常常做我们坐骑的背脊光滑的雄狮也不知逃进了哪座荒山。然而大门开着，照壁上“长宜子孙”四个字却是原样地嵌在那里，似乎连颜色也不曾被风雨剥蚀。我望着那同样的照壁，我被一种奇异的感情抓住了，我仿佛要在这里看出过去的十九个年头，不，我仿佛要在这里寻找十八年以前的遥远的旧梦。”

从这个开头可以看出文章中关于人生道路的线索是由什么引发出来的？
