You’re a busy engineering student. You hardly have time for sleep, let alone plugging back through those essays you had to write. (Essays you were forced to write for your liberal arts requirements. Essays that have already taken up valuable hours of your life that could’ve been spent sleeping.)

Combing over your writing with a red pen may seem like a waste of time, but it’s really one of the most essential steps in the writing process. Maybe you don’t have time to dedicate to a thorough editing job. But you still realize that an unedited paper is less likely to be good than an edited one. You know that some beta testing is in order. You know that it’s important to communicate your ideas efficiently and succinctly. And a good round of editing will help you do that.

Luckily, there are professional editors out there who will help you get a round of editing out of the way while you catch up on some much-needed sleep. That’s right: you can multi-task by sleeping and editing at the same time. And when you wake up, you’ll have detailed notes on how well your paper did its job of communicating your ideas. You’ll have a marked-up copy of that paper, full of notes about what revisions you need to make and explanations of why. You’ll have a personalized response, detailing overarching issues or strengths. And just reading over those notes will make you a better writer. Plus, your well-rested mind will be better primed to internalize and make use of those writing tips on your future writing than it would have if you’d stayed up all night poring over your own paper with your own red pen.

Sound too good to be true? Don’t be silly. Just hire a professional editor already.
