The beauty of the freewrite exercise is that the 5 minute freewrite is a loose requirement. The goal is to enable writers to release the inner critic and just free-write. We can extend the exercise as long as we desire. The last thing @mariannewest desires in this exercise is anxiety over the fun of creating. Let your writing go free and write as long as you like. You can even put a marker on the piece showing where the timer stopped if you like. I hope this explanation helps and thank you for sharing with us!
