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...
Don't know who you are (for however long you can stand it, you don't anyway, you only think you do).
Don't know what planet you are on (you don't anyway ... earth is just a name slapped on a giant ball floating in space).
Don't know what town you are are in (you don't anyway ... it's just a piece of land that someone separated out so taxes could be charged).
Don't know where you are going (you don't anyway, in truth you haven't moved an inch ever).
Enjoy the freedom of not knowing what anything and everything is for, you may just begin to smile more and care less.
