What kind of simple job/work do you think can you do when you are 18 years old?

I want to do something a little more active. Since I live in Busan, I want to do a job with a roller coaster at Gyeongju World! I sometimes memorize lines to do this. For example, \"Welcome to Gyeongju World Amazon Express! Be careful as the water may splash. Tighten your seat belt, keep your belongings behind, and hold the handles tightly, and then let\'s go!\" This line is from the \"Run BTS\" channel that BTS doing! When I saw this, it was so cool that I thought that if I could do a part-time job later, I would like to try something like this! Oh, do you know this line? \"Welcome to Everland Tea Express! Check once again that the safety equipment is in place, and let\'s dive into the unknown from now on? Let\'s go to Everland, the imaginary land~ Let\'s go!!\"
