Something from my sketchbook- the text in the picture says it all really. (If you can’t read it/my handwriting, it says: “Recently I was reading an article which described getting through psychological defenses as storming a castle or like peeling an onion. Here is how you storm an onion”). I debated adding some kind of siege engine, but didn’t have space really.
If you google “storming an onion” you only get one thing- people discussing how to understand an INFJ personality type on the Myers-Briggs system. That’s a pity, I wish there were more onion storming about.
