Acting and All That Jazz.....

Hello! I am a noobie. I am reading my Sunday paper, and would like to get some opinions about something. When I was young, I did some acting. Then, I got married, went into marketing, and that was my life. Now, in my fifties, I have returned to acting. Am I insane??? I must say, I have done some local theatre, some indie shorts and films — but this journey has been HARD. Insanely HARD. And, some of my marketing clients dropped me cause they think (I suppose) that I have gone nuts.
I love movies, love acting — love everything about it, and I am not half bad.

SOOOO – should I continue with my marketing biz, and wise up — OR, is it good that I am pursuing a long lost passion?

I have managed to get a listing at IMDB, a source reference for actors…

But all in all – I am questioning my choices…opinions appreciated.
