What jobs are good for uni students that don't like loud environments?

I need to get a job and I've been working since I was 14. I've worked in fast food, a restaurant, been a swim coach, and lifeguarded. I've even had my own successful online business.

The problem is, I found all these jobs incredibly stressful as they were loud, chaotic, and everyday was unexpected and changing.

I really want a job somewhere quiet. I don't mind working hard physically, I also enjoy repetitive tasks. Obviously I would prefer a higher payed job, but I'm not going to be picky because it's halfway through the year so a lot of good jobs have already been taken.

Does anyone know of some more peaceful / solitary work environments I could apply to?
