Get to quantity first. Quality is easier to find when you have a pile to dig through.

Judgment needs material to work on. A single attempt gives you nothing to compare, so you end up defending it rather than choosing from it, and the standard you apply is imaginary. Make thirty and the good ones separate themselves without much effort on your part.

Set a volume target rather than a quality target for the next stretch: ten drafts, twenty sketches, five songs. Do not edit while you are generating. When the pile exists, go through it cold and keep the three that still hold up.
