I'm in this (job) right now because I make a pretty good income so if the opportunity presented itself that provided a better means of financial support, you bet I'd quit.
I didn't get into this profession because it was my "calling" or life's passion....so getting out for the same reasons I currently stay seems a like a no brainer for me.
100% agree with black cat!
