Umm...well when you're a teenager your main job is a student. If 당신 have enough time to get a job outside of school, 당신 could work anywhere...Walmart, the library, Starbucks, a pet shop. Like I said before, how would I know what job 당신 want? 당신 should decide for yourself based on your interests as well as the pay and hours of the job.
P.S. If that's not what 당신 were asking, I'm sorry. :) It's just, your grammar threw me off...
