For the most part, my freelance career has consisted of long-term relationships with health professionals, fitness gurus, marketing pros, colleges, and others. These consistent, mutually beneficial relationships span months and even years.

However, every job I take on doesn’t result in a long-term relationship. I’ve edited books for writers who wrote a single book and never written again. And since I added resume writing to my services a few years back, I’ve come to have quite a few one-off clients. After all, the goal of a resume is to help an individual gain a new occupation they can maintain for the foreseeable future. As such, resume writing often doesn’t bring about repeat business. Sometimes, however, it does.

One of the most exciting repeat resume clients has a professional background. He told me that the resume I built for him helped him land the job he wanted and now he needed my help again. This time, however, he didn’t need a resume for himself. He needed it for his son, a college student who has his eyes set on landing an internship. And no, this is not just any internship he wants. He wants an aerospace engineering internship. That’s right—the little guy who writes and edits out of Cleveland, Tennessee, may play a role in helping someone get on Mars.

Should this University of Tennessee student get that internship, touching the moon’s surface may be the least impressive feat he could accomplish. With brains like his, he may transform how we communicate. Or maybe his future career will open the door to safer, more efficient transportation.  Then again, he may find a way to build a robot that looks like a roommate but pays an equal share of the rent and doesn’t leave dirty dishes in the sink. Regardless, he’s obviously going to do big things. And it’s humbling to think I may have played a small role in moving him in the right direction.

So the next time you look down on your resume, remember that if done well, your resume may be your ticket to the moon and back.
