Anytime I audition for something, it's always a question of whether or not the people I'm auditioning for understand I'm an improviser and I like to do that, and if they like that or if they just want someone who's going to do what's written.
You have to decide what is extraneous and what is central. There is always more to tell. If you want to have a finished product, at some point you have to say "enough."
You will never get to the irreducible definition of anything because you will never be able to explain why you want to explain, and so on. The system will gobble itself up.
Count all th' advantage prosperous Vice attains,
'Tis but what Virtue flies from and disdains:
And grant the bad what happiness they would,
One they must want--which is, to pass for good.
