I have good friends who work at law firms making six figures who complain about never having money.
None of my actor friends make more than 25K a year (save the lucky ones who are in Bway shows right now), and we go out and drink and have fun and see shows and pay our rent and bills on time.
It's always an elaborate dance no matter what you do, so...the trick is knowing what you can't deal without...and making sure you work hard enough that you can earn that.
I should also mention that if you are coming here to persue theatre, know that you will always be working two full-time jobs -- that is 80 hours a week...one job persuing your next gig, and one job that pays the bills. That is, unless you get lazy and just do one or the other -- which results in either losing out on your home or losing out on your dreams.
