PA reports that the actress, who has portrayed Maria Connor in the Weatherfield soap for 11 years, told an audience at the launch of the Home Heat Helpline's winter campaign that she never forgets how lucky she has been to have a successful regular job.
Smith explained: "I think it's just all sorts of luck and circumstance that get you to where you are now. I suppose everything happens for a reason.
"I don't take it for granted at all. Fortunately I'm in a position where I don't need to worry about my fuel bills, but never say never... if I wasn't in Corrie I'd be a jobbing actress, struggling!"
She added: "When I see dramas on the telly that I really enjoy watching I have a moment where I think, 'Oh that could be nice', but Corrie's been brilliant and I can't complain at all with the storylines I've been given.
"It's every actor's dream to be given challenging stories so I'm happy there."
