A bad one

Yesterday, after a string of good performances, I had a really bad one. I hadn't slept well, I discovered that going to bed late and waking up late doesn't really do for me, so
last night I went to bed at 11pm and this morning I woke up at 8.30am. So rock-and-roll. The heath in my venue was also particularly unbearable and chance had put together an audience mix that seemed to react weakly to even my strongest jokes. It's very difficult to say to what level is your performance and what level is the audience, since what happens in these cases is some sort of vicious circle, where a weak response to something originally delivered reasonably well makes you loose confidence and concentration, leading to a weaker delivery and an even weaker response. Of course the right reaction would be to do the opposite, to step up your game in front of the adversities, but I guess this is one of the things I'm here to learn. Today I feel more rested so let's see.
