Quickly generate an illustrated list/collection of ten (10) ideas. Keep each idea simple, draw whatever comes to mind first. Do not worry about whether the ideas are good or not. They just need to be simple and different than each other

Revise your list so that only five (5) revisions remain. Do not think too hard about this, just quickly eliminate each idea you do not like until only ten are remaining in your collection

Make a new version of your illustrated list / collection, this time of your remaining five (5) ideas

Pick one (1) of those remaining five (5) ideas to actually pursue / make
