There is a difference between knowing and knowing.
We all, for instance, know that it's hot in the desert. For most of us, this is the one thing we ever know about deserts. Whenever deserts are mentioned, the knowledge that deserts are associated with warmness is instantly summoned to our attention.
Yet if we should actually find ourselves in a desert, I have a feeling that the first impression might go something like this: HOLY MOTHER OF JESUS CHRIST SUPERSTAR IT IS WARM IN THIS DESERT, WHY DID NO ONE TELL ME OF THIS?!?!?!?!
There is a subtle difference between knowing and knowing.
I urge you to explore and hack this difference whenever possible. You'll be surprised, you know.
