Will I(18) hurt myself later on in my life by quitting my job at Walmart 4 months in?

I've been working at Walmart for 4 months now. I like my co-workers and have no problem with my management, but they just make me work so many hours and I work as a cashier which is just awful sometimes. I feel as though I have no time for school and things I enjoy. It's either come home and spend all my time on school work then pass out or practice my hobbies. I'm currently in school for music education. Will me leaving my retail job of 4 months hurt me later on when trying to apply in other industries?
