When you think you don’t understand something, there’s always some part of it you do get.
Write a page that shows how your mind can be full of understanding and not understanding all at the same time.
Write sentences that have this form:
I understand _____, but I don’t understand _____.
Don’t strive very hard to write ideas that are connected. After all, you only understand half of what you are writing about!
When the page is full, give it a title. Put a signature and the date on it, too.
