But as soon as you start to think about screwing up, you trip. same in performance. if you wonder whether you recall the lyrics you’ve taken a detour to swamp road, disaster waits. trick is not to let those thoughts take over. in improvising too. to think about it, to raise inner doubts about it – game over. maybe the trick is knowing the main route so well, so inside out, that it is effortless to stay on it.
