Of all the lessons I learned in my college days — at least of the ones I’ll admit to in a public post — one of the most important was the value of rewriting. A first draft is just that — the first shot at getting everything organized on the paper (or onscreen). Rewriting gives you the opportunity to refine and improve what you’ve done.
Sometimes, people ask how many times they should rewrite something, and my answer is always the same: however many times it needs. That’s not a flip answer. At times, one rewrite is enough to make something work, while other words might need to be trimmed and polished a dozen times.
