This sounds like an assignment given to prepare you to get the most out of a writing class. Well, do you know any examples of attributes that make a writer a "good" writer? This is all about your own ideas, and they may change during your class.
Tell me your strengths as a person, and I'll tell you your strengths as a writer. For example, you may have the insight that you are a concrete thinker rather than an abstract thinker, so you have trouble mustering up some creative story but you ARE good at thinking methodically and communicating is a clear, direct way. Or, it might be the opposite.
If you are young and do not have much experience writing, that does not mean you lack strengths. Then again, a lack of experience can be a weakness.
Do you read a lot? Being a good writer has a prerequisite: reading a lot.
Anyway, the "correct" way of writing this kind of essay is to just be honest and dig deep. Let the instructor know you and your ideas. If you lack confidence, her her/him know that, too!
If you want to be impressive to the instructor, get a copy of Strunk and White, or anything by Diana Hacker, and list as one of your strengths the fact that you are now studying that book.

Also, it is a strength that you are amemeber of EssayForum!
I agree with kevin, and the others!
first off we need to know more about you and see the essay you are planning to write.
Besides that there are many things that make a writer successful or unsuccessful. Usually your traits can dictate which one you are.
