Stop!! Think about where you are right this second in your career plan (hopefully you have a "plan" - if not, this is a good time to think about that).
Once you've assessed where you are, ask yourself if you have the next right audition for that timeline.
1. You've got some good Young Artist Program experience under your belt, a few regional roles, but no management - is this the time to contact or recontact a manager to hear you?
Perhaps so - if you don't have that audition lined up, look into it.
2. You've hit a bit of a wall with auditions, and you feel like some technical work out of the pressure of the professional audition circuit makes sense, and you've considered looking into an artist diploma program to help make that next step happen. Have you explored this? If not, now is the time to do it!
You see my point - don't let too much time elapse between taking "snapshots" of where you are, so that you can take the proactive steps that are needed.
