How much writing is required by people working in your career area? The best way to learn about on-the-job writing is to talk with someone who has a job similar to the one you hope to have one day.

Interview someone working in your field of study. Your instructor may ask you to present your findings orally or in a written report. Ask questions such as these:
What kind of writing do you do? What kind of planning do you do before writing? Where do you get information?
Do you brainstorm? Make lists? Do you compose on a computer or on your iPad? How many e-mail messages do you typically write in a day? How long does it take you to compose a routine one- or two-page memo, e-mail, or letter? Do you revise? How often? Do you have a preferred method for proofreading? When you have questions about grammar and mechanics, what or whom do you consult?
Does anyone read your drafts and make suggestions? Can you describe your entire composition process? Do you ever work with others to produce a document? How does this process work? What makes writing easier or harder for you? Have your writing methods and skills changed since you left school?
