I have been an actress( Theatre, Film, TV)  and a Director of Theatre for many years and never really thought about the merits of it until I started teaching acting classes.  Why we do what we do and does it really matter or does it matter that it matters etc.....Until one day, I was teaching an acting class, when I had a particularly challenging student in front of me and I had to stop and re-think my approach; what was I going to tell this actress...she was just not very good no matter…
