By “doing exercises”, we help training our “intellectual brain” and “artistic brain” to work hamoniously; searching for the joy and freedom in creating.
You need - well there's a considerable amount of intellectualbrain power in what they're trying to design better cars than Ferrari and then the trick is to operate them better - a tall order but it is possible and we're trying to do that.
You end up constantly on guard, with your adrenaline pumping to the fight or flight responders in your brain, leaving your best intellectual power untapped and unavailable.
