When I was little, I always wanted a luxurious house. That was my idea to be successful. I took all the classes with full carefulness 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 dream house. All the way through junior years, my mind was planning this wonderful future.
Then in the tenth 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.
