Extracurricular Essay - Writing about Work?

The prompt for Georgetown’s extracurricular essay says to write about a “school or summer activity.” Would paid work be a suitable subject, or should I stick to activities like theatre, volunteering, etc.?

Thanks in advance!

Pick a topic that will make you stand out; most kids have summer jobs. If your job was a unique experience (internships and things of that sort) or made some great impact on you then it potentially could be. If it were me, I would choose an activity that most applicants would not have done.

Thanks for the help! I chose to write about an intensive film class I took as an extracurricular, I hope it stands out.
