In the world, one receives praise and acclimation for knowing things, and there is nothing wrong with knowing things. However, every once in a while, allow the possibility that you do not know what anything is for. Become empty of knowing, you can always pick it back up.
For the sake of some fun...
Enjoy the freedom of not knowing what anything and everything is for, you may just begin to smile more and care less.
