I assume a music teacher can still explore music while paying the bills by teaching beginners?
Just fyi, I have nothing against teaching beginners. In fact I enjoy it. I don't even actually mind the inundation with Halloween music I've recently had (though probably out of self-preservation shouldn't have had quite so much of it), and I don't mind having Jingle Bells be next. And, while I in fact still do have a variety of students who, together, pull on a somewhat varied pool of what I actually have to offer, it is still very possible for the balance to be too far in one direction and it is.
When too many things happen at once or in a short period of time that make me wonder why I am doing what I am doing, then it's pretty challenging. I give a lot of myself to others. A lot. And I am not one of those teachers who makes a special point at every turn to make sure that my students understand how privileged they are to be working with me and how worthless they are

. And I do not currently have any form of truly feeding my own musical interests. My path with music and teaching is not paved with awards, pats on the back, and special recognition for my accomplishments, so almost all of what I have ever done has been generated from within. In fact, certain people that I have cared about a looked up to have made special points to help me thoroughly understand that what I do as a musician and person have next to no value to them, including a special phone call near my graduation that informed me this individual wouldn't attend graduation as they normally do, because I was the only student of theirs graduating. For people here to act as though I am some spoiled person who has always had things go my way or who is, for just a slight moment, trying to do something without the show of approbation by others, are just uninformed and completely clueless.
It is also not true that the teaching I do allows me a bunch of extra time to pursue what is of deep interest to me, and I just don't think it's true of teaching in general unless a person has a quite cushy teaching job. And even if it did, what would the application of that knowledge and growth be? Even though I love music -beyond words- it is not ultimately about being self-serving and I don't get the full satisfaction by studying and learning without a useful application that includes or at least potentially includes sharing some part of it with others.
My morning today consisted of me sitting for some moments just to emotionally and intellectually balance myself before the work day (I find this is required to do my job as well as I can), to momentarily ponder the possibility of personal time at the piano, but to come to grips with the need to instead make learning tracks for my singing class to sing Bohemian Rhapsody (in which class I have a mixed bag of individuals who think they are much holier than the class and people who are happy to be there), to do more grading, to clean my teaching room, make some phone calls, answer some emails, and then teach starting in about 15 minutes until 7pm this evening.
I can actually remember what it was like to not be musically able to do the things I described in the paragraph above, and to in some ways be locked into any of the jobs I had before this. I am grateful for my job, I even ultimately do like it. I simply would appreciate the possibility to grow, to learn more, and to apply more of who I am. At least, as of the last hour, I am picking myself up a bit and considering climbing back into the hamster wheel.
