Japanese work

You wouldn't believe me. Two years ago, I started to work a part-time job for the first time. I used to work as a teacher of sub-school , where is a school that some students go after secondary school , and was teaching English in man-to-man for secondary school students mainly. In Japan, we study only grammar in school, so I didn't have to speak English at all in the sub-school and haven't done any preparation. Because I was catching a glimpse of student's textbooks they brought when I had forgotten any grammar. the job was also well-paid , so I felt easy and lucky although I think actual teacher is hard job and different. But I couldn't work for a long time: three hours at best. In those days, I wanted to earn more and more to rent a room of an apartment by myself, so I worked in a kitchen of a restaurant for six months. I didn't know why I was adopted, because I hadn't been used knives until then and I couldn't distinguish from any vegetables or meats. But my senior colleagues taught me very very kindly. Maybe they must've been quite stressed, though, thanks to them, I could learn useful skill in the kitchen. This job was well-paid as well. However, it was really busy and hard job. I had to work eighteen hours a day, including two hours brake although I was working the job three times a week in a row, so I was dying every half a week in that days. As a result of it, I felt happy whenever I checked my bank account and could rent a room immediately. I no longer want to work that kind of job, but I was blessed my colleagues and had a good experience.
