Do things that keep a foot in the door. Besides the private lessons, I played in a community band where the local band directors could hear me play. Your playing skills are still important if you intend to do Band. I once did an interview with an honor band program that had me play an impromptu recital during my interview. No warning, just handed me a flute and said play. Four songs later, I had the job.
My elementary experiences definitely made me a better band director but I eventually found the intensity of an 8-4 elementary job much more exhausting than a 12 hour a day band job. Learn what you can from your current situation. If it is nurturing you, stay. When it stops being nurturing, spread your wings and fly to a job that will. Good luck!
