Creating without picturing

Aphantasia doesn't mean no imagination. A mind can build new things through sound, words, structure, movement or by working directly on something real. A useful way to look at it is task by task: does what you're attempting require generating an image from nothing, or can you work on something that already exists? The first kind is often a struggle. The second can be where people with aphantasia do very well, because there's no internal image competing with the real one. Ask what a task needs you to do in your head, then find an outside version of that step.

CJ Stewart's book explores this idea chapter by chapter.
