Is it possible to perform in local theater while also pursuing a demanding career?

Yes, however there are many implications that should be thought through, as theater (even at the local, unpaid volunteer level) is a time-consuming and rigorous hobby. 1) Career choice. Restaurants, retail and other careers that required nights and weekends regularly often conflict with rehearsal and performance schedules, which are often all on nights and weekends. 2) Travel. Planned, infrequent travel can usually be planned around. But if your career requires spontaneous travel on a moments notice, it may be difficult for you to commit to the rehearsal and performance schedule, which is often planned months in advance.
