You should always be either at the edge of your traction circle or at the full limit of one of your controls. Anything less is wasting time.
This notion of limits and edge reminds me of Hunter Thompson's musings on "The Line" in his piece about the Hell's Angels. He argues (wildly paraphrasing) that the fundamental draw (and in some sense, the art) of motorcycles or extreme sports is in finding that edge or limit. The problem he identifies being that you cannot really know where it is without going over it, with all the consequences. https://en.wikipedia.…

"One of my finest addictions" indeed.
