That's something I have to work on: to separate what really matters, to conserve energy by not worrying about what other people think.
'Sherlock' fans are, by and large, an intelligent breed, so they've gone through my back catalogue and got what I've done, why and how I've done it. There is some obsessive behaviour, but I worry for them rather than me.
Any irrational fears?no, i'm quite a rationalist. i'm not superstitious, i think life is too full of natural wonders and logical complexities to worry about illogical things.
I tend to have a cup of tea, try to stop worrying about what I did wrong, cool down and will the audience back in as soon as possible.
