     "Confidence" is probably one of the most noticeable traits (品质) in the Americans. They show

confidence in the way they talk, the way they smile, the way they dress and the way they walk.

Living and competing with all these confident American students, I find it extremely important to

be confident as an international student and instructor. As a student, being confident means you

should never hesitate to raise your hand whenever a question or a point comes to your mind.

Don't mind if it sounds simple or silly. Otherwise you will never get a chance to speak in class at

all. What's worse, the professors may think you are not prepared for the discussion or you do not

have your own opinion on the issue-this is the last comment any graduate would like to receive.

     Being confident for me as a foreign instructor means calmly asking the student to repeat what

he or she has said if I did not get it. Pretending to understand what you actually did not may just

bring yourself embarrassment or even disgrace. But the time I most need to be confident is when

my students come to my office and bargain about the grades I have given for their speeches.

(The course I'm teaching here is Public speaking). Modesty is a trait highly valued in China, but it

won't be of much help here if you want to survive and succeed in a good American graduate

program.
