I was half-reminded of a quote by yesterday's coffee morning, but then I couldn't find it.
Well, I found it. Somebody (I can't remember who) said this to Maureen Lipman:
"It's not your business as an artist to judge the results of your labours. Your business is to keep the channel open, let the life force out. Judgement will just block it."
To which Ms Lipman replied: "But what about satisfaction?"
...and was told: "There is no satisfaction. Just queer, divine dissatisfaction."
I like that.
