I retired a part-time job

I retired a part-time job which drug store in this summer vacation. I worked there for about 7 months. The reason I retired it that it have to go to work 15 times a month. It was very hard, in addition, it finishes about 0: 30. I have many homework in school, so I was very busy. I think, this decision was not wrong, but now, I  don't part-time job so I can't earn money. Because I have many homework, I think I should not do part-time job many times, so I want to do it somewhat less than until now.
