When you begin to write, use the information you have gathered to compose your first draft without too much censoring. Let it flow freely. Nothing should be out of bounds. Getting all of your witticisms and thoughts on the page is more important than grammar at this point.
For some personalities, it is hard not to red pen as you write. Try to learn to throw caution to the wind and you might find you write a sentence or two that enhance your piece which might have been otherwise cut before they were given a chance.
After you have drained every last drop of inspiration for the article then you can bring out the scissors. There is an art to editing as well. You don’t want to cut too much out and lose the main point of the article. Editing haphazardly leads to disjointed sentences that don’t follow a train of thought the reader can get behind.
Editing is an important part of writing but it has its time and place. Keep your desire to edit in check until you have fully expressed your ideas.
