Some books need sanding down. They should be fast and smooth and take you on a ride.
But not all of them.
Some books need edges. They need to hook into you, so you'll come back to ponder and think. These books are tools, filled with truths and insights on every page. They are the kind we want to revisit often—that will sharpen our brains and soul.
Books can be funhouse rides or well-worn tools. We only need to understand which one we are writing.
