There are many ways to be involved in the arts besides performing your art form. Getting to know the business side of the arts can be fulfilling. Theatre is a risky career to go into, although very worthwhile. Few of us actually make a living in it. You can hone your craft even if you are doing something such as creating training videos for the corporate world.
Careers can take unexpected turns.
If you are thinking about graduate school, there are graduate programs in the field of theatre as well as other professional degree programs. Then I had the opportunity to go into arts administration as my day job and this was such a good fit that I stayed. My very first job was an internship at the Guthrie Theatre. I also volunteered for local community theatres and held some paid non-theatre work at first. Of course, Grinnell's Theatre Department provides advising as you consider questions about your major, internships, gaining experience, and making career decisions.
