     During my high school years, the most important thing was what I was wearing to the Friday night

dance and who I was taking. Although college was talked about, it was the least of my worries.

     When I was graduating eighth grade and starting high school, my older brother was graduating

twelfth grade and going onto college. For my graduation, he gave me a card in which he wrote, "Enjoy

your four years. . . They go by fast." I remember not believing him then, but looking back. . . He was

right. Those four years shaped who I was as a person, pushed me to my limit and encouraged me to

become an adult.

     However, I was so completely absorbed in my junior and senior years of high school, that when

someone spoke of college I brushed it off. I wasn't ready to leave my comfort zone of having all of my

closest friends together and knowing what every single day was going to be like. Studying was something

I did only AFTER I nailed my halftime dance performance. I knew my parents wanted me to go to

college, so I told them I would go to community college (社区学院) and I didn't worry about my SAT

(美国大学入学考试) scores.

     When my senior year passed and everyone graduated and went off to their own colleges, I started to

wish I had done the same. My friends were living away, meeting new people, and discovering new

places, while I was living at home and driving to and from class every day. It seemed exactly like high

school. I hated it!I thought college was supposed to be different!Why didn't I take more time to

research colleges and do the same?I ended up loving college and wishing I had four years to enjoy the

campus (大学校园) atmosphere instead of two.

     My advice to anyone thinking about attending college is to think about it very seriously and look into

all of your choices well ahead of time. Now I have graduated and I am working fulltime and I would do

anything to go back to my high school days for a second chance!
