Like many other high school seniors, I eagerly anticipate life after graduation. In less than three months, my belongings will be packed up and shipped to the other side of the country.

I had never imagined, in my wildest dreams, that I would attend college in Ithaca, New York. I had had my heart set on a university in California and of majoring in English.

Nearly all of my friends are staying in state, and I remember thinking to myself, when one friend said she would be going to college in Virginia: Why would someone ever choose to move away from California?

But by a twist of fate, I received a letter from Ithaca College, inviting me to apply for a program in communications. On a while, I decided to apply. What were the chances that I would be selected as a finalist? If I hadn’t applied, I would have always regretted not trying. Yet secretly, I hoped that I wouldn’t be chosen.

But, as things turned out, I was offered one of the scholarships. I also received admission letters from the other colleges I had applied to, all of which were California schools.

As I began to weigh my options, I wrote out a pro/con (利弊) list for each of my schools. I began to realize that my reasons for wanting to go to certain schools in California were based on considerations of comfort. It would be so reassuring to be close to my family and my home.

Then I began to think about the expensive tuitions (学费) and class shortages in the California public school system. These issues were not likely to greatly improve in the next four years. Slowly, I came to the conclusion that Ithaca was the ideal choice for me – culturally, academically and financially.

Fear of the unknown should not be a reason for shying away from opportunities. It might be difficult to adapt to my new situation, but I am confident I have made the right decision.
