Ed Boyden on How to Think "in a world where problems are extremely complex, targets are continuously moving, and our brains often seem like nodes of enormous networks that constantly reconfigure".
Make your mistakes quickly. You may mess things up on the first try, but do it fast, and then move on. Document what led to the error so that you learn what to recognize, and then move on. Get the mistakes out of the way. As Shakespeare put it, "Our doubts are traitors, and make us lose the good we oft might win, by fearing to attempt."
