In two years, you won't be an apprentice anymore.
Enjoy making good money for little work, and realize, that your happiness will be short lived once you actually finish and have to work. Suck it up.
If the apprenticeship is for a job you don't want to do, then leave it and figure out what it is you want to do.
If you quit, you will have wasted a tremendous amount of time and money, so make sure you are doing what you want to be doing for the rest of your life.
