So Saturday I worked for about 4 hours on revising my latest YA, adding two whole chapters that were absolutely brilliant.

On Sunday I deleted both.

The time was not wasted, anymore than  time was wasted when I practiced overtones on my saxophone for 45 minutes. (Rose claims it was closer to a million painful years, but I'm sure it was only 45 minutes.) It was a good exercise and by getting it out on paper, I got to better evaluate the plot change, which turns out to be meaningless and too off topic. So it gets cut. And that's good too.

Knowing what to cut is just as important as knowing what to keep.
