It needs to be good enough for it to be as good as someone wants it to be.
For example…
The show has to be good enough that the person who wants it to be amazing can reasonably think it was amazing.
And maybe the truth is it wasn’t the most amazing show…Maybe there were mistakes and missed notes and some sloppy transitions…But if it crosses the threshold of good enough, then it can fill the ‘amazing’ expectation of the audience, even if it wasn’t.
Same goes for food, paintings, graphic design and all the other creative endeavors that we make careers out of.
It has to be good enough to be what the audience was hoping for…even when it isn’t.
