An artist paints a canvas and moves on.
Art stands for itself.
The artist does not stand next to their work in an attempt to convince you of its merit.
I am beginning to feel the same way about writing a book.
One idea is to write a page at the back of the book about how to use it.
For example, choose a passage from the book to read aloud to a group. Then let the rest of the group talk about what it means to them before it’s your turn to talk about why you chose the passage.
