Just for fun, I deleted 25,000 words from a novella (that would be the whole novella) and started over with a new plot. I outlined this one in advance. It wasn't good enough.
When you wonder why your favorite author isn't churning out six or seven books a year, this is why. No one wants to write just OKAY books. An author wants to write the best book possible, even if it means scrapping everything and starting with a blank page after five months of work.
