Writing may be used for either of two broad purposes – to discover ideas or to communicate ideas. Most of the writing you have done in school is undoubtedly the latter kind. But the former can be very helpful, not only in sorting out ideas you've already produced, but in stimulating the flow of ideas. For some reason, the very act of writing down one idea has a way of producing additional ideas. Whenever you write to discover ideas, focus on the issue you are examining and record all your thoughts, questions as well as assertions. Don't worry about organization or correctness. If ideas come slowly, be patient. If they suddenly come in a rush, don't try to slow the process down and develop any one of them, but jot them all down. (There will be time for elaboration, and for correction, later.) Direct your mind's effort, but be sensitive to ideas on the fringes of consciousness. Often they, too, will prove valuable.
