1. Be careful to stay on topic. If you are writing about something unimportant, you may find that your main message becomes buried under trivial stuff. This makes editing particularly important.
2. Be sure that your writing is well organized! Poorly organized writing may not read well and may even confuse your readers. As you go from paragraph to paragraph, check for cohesion. Try to organize your paragraphs into some kind of logical order.
3. Writing takes patience and practice.
