For the improviser it is: ready, fire, aim. We begin before there is a plan. What we do moves us forward and gives us more information about how to proceed. The doing itself becomes the teacher and guide.

Even spontaneity gets better with practice.

It’s not an either/or, it’s a spectrum. You never want to close yourself off to happy accidents, but you want to have some stuff up your sleeve no matter what. And you’ll always have to rethink things in revision.
