When I get lost in despair or fear or anxiety, I take great comfort in evolution. I take great comfort in the knowledge that I am the product of untold years of experimentation, of trial and error, of determination, of savvy, of instinct, and of plain old dumb luck. No matter what particular demons I happen to be wrestling at any given time, the inhabitants of those untold years have seen them, fought them, and survived.
I've no doubt that wisdom lives still in the rivers of our blood, is built into the structure of our bones and woven into the elasticity of our skin. We have everything we need. We have the history to prove it. Now, we just need to remember it, and then to believe it.
