Mọi người làm giúp mình với ạ( không sao chép mạng nhé) Describer a part time job you have done in the past

Being a 18-year-old girl, I have done about 2 part time jobs since I was 15 but th job I like most was being a bookseller in a bookshop near my house. It was my first job, which means I worked as a seller when I was 15. To be honest, it had enormous benefits. First, the working time was not much so I can manage time between work and study well. Also, the shop manager allowed me to study and read books there when we had no customers, therefore, I can enrich my knowlegde a lot. Frankly, working here brought me a brunch of information from needle to elephant. Moreover, I could learn how to treat people when being a seller. This is due to the fact that customers have different hobbies and different ideas about books so I was taught how to behave properly and make customers feel pleased, which are necessary skills I need when coming towards university in the future. Last but not least, by working part time, I can earn some money for my daily expenses which helps my parents somehow in the family finance. In short, I had a lot of fun and life skills when working as a bookseller.
