Well, I do have *other* interests. :P Playing music, reading books, baking delicious food, catching up on various TV shows, hanging with friends and family...
If we're being literal with "Broadway", then I quell the theatre-going urge by going to the West End. If we can use the "the major theatre capital on your side of the Atlantic" definition though, then I chat about theatre online, read playtexts, listen to cast recordings, and indulge in my other interests so I don't get completely burnt-out on theatre. :)
