I had the honour of coaching a very well known television presenter recently who is making a cross over into acting.
Having never acted before she was remarkably gifted, specific and instinctive.
Anyway, mid way through some impro work, she was struggling to let her imagination fly and kept blocking herself.  She wasnt easily able to mix fiction with reality.

After explaining to her that she may benefit from treating her stage relationships like a structured game, bypassing her own limited experience, she suddenly lit up and said “oh, so its me… without restrictions! “
Yes!! What a lovely way to access your onstage freedom, ‘me without restrictions’  I liked that and, as I told her, am taking it for myself. Everyone is your teacher!
To you, the artist.
