I started to understand what 'letting people come to you' means, and how it actually relates to voice and body technique.
In 'Voice and the Actor', Cicely Berry - voice director of the RSC - writes about the importance of working with one's own voice instead of trying to 'correct' it or 'make it better' (sic)
"I think one of the greatest fears of the actor is that of not being interesting. This really need never be a fear because everyone is interesting in that he is himself. When you get to the point which says: 'This is me; it will change and perhaps improve, but this is me at this moment', then the voice will become open."
