Life IS Brownian motion! Just random motion of particles that we bump into and react to. That's awesome!!

Acceptance is the best response. Accept life as it is and let go of expectations.

Carl Jung wrote, "“We cannot change anything until we accept it. Condemnation does not liberate, it oppresses.”

For me, happiness is about accepting 'what is' and letting go of what I can't control. Which is SO HARD to do (let go of the outcome I want). But it's like the Serenity Prayer reads: "...grant me the serenity to accept the things I cannot change, courage to change the things I can, and the wisdom to know the difference."
