     Engineering students are supposed to be examples of practicality and rationality, but when it comes

to my college education, I am an idealist and a fool. In high school I wanted to be an electrical engineer

and, of course, any sensible student with my aims would have chosen a college with a large engineering

department, famous reputation and lots of good labs and research equipment. But that's not what I did.

     I chose to study engineering at a small liberal arts(文科)university that doesn't even offer a major in

electrical engineering. Obviously, this was not a practical choice; I came here for more noble reasons. I

wanted a broad education that would provide me with flexibility and a value system to guide me in my

career. I wanted to open my eyes and expand my vision by interacting with people who weren't studying

science or engineering. My parents, teachers and other adults praised me for such a sensible choice. They

told me I was wise and mature beyond my 18 years, and I believed them.

     I headed off to college, sure I was going to have an advantage over those students who went to big

engineering "factories", where they didn't care if you had values or were flexible. I was going to be a

complete engineer: technical genius and sensitive humanist(人文学者)all in one.

     Now I'm not so sure. Somewhere along the way my noble ideals crashed into reality, as all noble

ideals eventually do. After three years of struggling to balance math, physics and engineering courses with

liberal arts courses, I have learned there are reasons why few engineering students try to reconcile(协调)

engineering with liberal arts courses in college.

     The reality that has blocked my path to become the typical successful student is that engineering and

the liberal arts simply don't mix as easily as I assumed in high school. Individually they shape a person in

very different ways; together they threaten to confuse. The struggle to reconcile the two fields of study

is difficult.
