Our school encouraged is to experience some future careers last vacation. Some students choose to work as either cashiers in a store and waiters at a restaurant. I was one of the 500 student to join in the activity. I decided be an assistant in a photo studio because of I love taking photos. With the help of a advanced photographer in the studio, I opened my imagination in my daily work. I also developed practically skills which are necessary for them to face future challenges. The most important thing I've learned are to improve myself after I get my dream job.
