       在电视上，观众看到了宇航员科马洛夫镇定自若的形象。他面带微笑地对母亲说：“妈妈， 您的图像我在这里看得清清楚楚，包括您头上的每根白发，您能看清我吗？”“能，能看清楚。儿啊，妈妈一切都很好，你放心吧．！”这时，科马洛夫的女儿也出现在电视屏幕上，她只有12岁。科马洛夫说：“女儿，你不要哭。”“我不哭。”女儿已泣不成声，但她强忍悲痛说，“爸爸，您是苏联英雄！我想告诉你，英雄的女儿会像英雄那样生活的。”科马洛夫叮嘱女儿说：“你学习时，要认真对待每一个小数点，联盟一号今天发生的一切，就是因为地面检查时忽略了一个小数点……”

When I was young, I wished for a good car and a big house. That was my idea of success. I took all the advanced classes and tried to do well in the exams with my mind set on going to a key school. I just knew that I would somehow become famous and be able to afford the car and the dream house. All the way through junior years, my mind was planning this beautiful future.

Then in the eleventh grade, many losses changed my mind. First, one of my friends died at 16. Soon after, my great-grandmother passed away, followed by my beloved fourth-grade teacher. These events left me not knowing what to do or where to go . Death had never touched me so closely.

After a long period of emptiness, it finally struck me: Life is not promised and neither is future success. Though I was attempting to achieve material success, I was not enjoying my daily life. I realized that finding inner peace, purpose and happiness will stick with me forever and that is real success.

Enjoying life's precious quirks ( 偶发事件 ) makes an ordinary person more successful than a wealthy person who isn't content and takes everything for granted. The summer before senior years, my attitude changed greatly. Instead of memorizing facts, I began learning skills. Instead of focusing on the future, I focused on today and the many blessings and successes that came with it.

I still get excellent grades, but now I devote weeks to studying instead of struggling for exams, and I think about the future with a deeper sense of meaning. For me, being successful means truly living life each day.
