I haven't read the other posts. Sorry if I'm repeating.

You probably only have what, a year or two left? Right now you're probably thinking it would be great, you don't need it...but what if someday your grooming job goes down the drain? or it's not enough? Someday you might regret not finishing school. I've known people who did the same and later regretted and had to go back for their high school equivalence or whatever it's called. It's up to you but try thinking of all options.
