Often actors ask me if I think they should go on trying to be an actor.
I have the same answer for everyone who asks: If you have a choice and could reasonably be happy doing something else, by all means go at once and do something else.
Acting or writing or directing in the theatre or television or screen is only for the irrecoverably diseased, those who are so smitten with the need that there is no choice.
