Even with a paper assignment that only calls for two to three pages, there is a need to revise and expand. Your first draft likely has one page. To move to two or more pages do the following:
Using a printed draft, silently reread your draft with a pen or pencil in hand. Simply listen to your words, marking any rough spots. Sometimes 24 - 48 hours can give you a slightly new perspective on how you presented your subject.
Now, use the feedback as a starting point: consider what was said and see if you can react. If the dominant impression wasn't strong, consider your diction (the words you chose). Could those words or phrases be enhanced and expanded? Do you know why those words and phrases did or didn't work well? Do you need to use different words (or even details) to reshape your purpose? Give yourself time for this step--you're trying to answer the question, "Why am I telling my readers about this subject?"
What was strongest in your draft? Could you do more of that? This is especially true if
your feedback singled out the same thing.
Even as you expand, work on diction. Rereading should give you a chance to hear where descriptions might be weak or bland. This is especially true of your verbs. Of course, "to be" verbs (is, are, was, were) are inevitable, but they shouldn't dominate.
Consider your draft's structure. Most profiles have either a topical or chronological organization. When you see how you've told your story, work on strengthening the organization to give your paper a clear beginning, middle, and end.
Work on the introduction.
This is your hook to bring your readers into your profile, so think about
how you would like to begin. Then, see if the finish is as good as you would
like.
At this stage, you can work to
clean up the mechanics. Of course you can and should do this just before you
call the paper done, but fixing things as you go along (especially if
readers have pointed out some problems) is a good idea, too.
