This has been a most interesting thread to follow. I don't know if I
can add much more to what anyone else has said, only that I feel the same
crunch almost daily.
I, too, work in a part time position. I stopped teaching art full time for
the very same reason--no time to do my own work--and it is remarkable how
much there is still left to do at the end of a day at school, which is
totally unrelated to the teaching of art to students.
I don't know what the answers will be for you, but for me, I found an
answer I could live with after reading the autobiography of Stephen King "On
Writing" is the title of it, if you're curious. To paraphrase it, King says
something like--life is not a support system for art, it's the other way
around. (So there you go, art is a support system for life.) I had to think
about that, and I realized that I am no good to my students, my family, and
certainly not to myself if I'm not creating. I could tell none of my
students what an absolute joy I felt while doing my work--how very much art
meant to me--what my passions about art were or how to set goals/follow
dreams if I was not able to do it myself. Granted, other things will fall by
the wayside, but sometimes, that's okay, too.
Best wishes always and happy creating.
