I'm thinking of quitting my apprenticeship early.
Why do you want to quit early?
I don't like it. I'm bored and I'm thinking of switching jobs.
It's reasonable to quit your job or apprenticeship if it isn't making you happy. I think you should try to do something that you find fulfilling.
School is way too much work. I don't have time for work and school.
That is okay to do. If you are uncomfortable you should find something that makes you happy instead.
