Why: Progress is built, in effect, upon the necessary foundations of failure. That is the essential paradox of expert performance.
Quote: The iceberg illusion – when we witness extraordinary feats we are witnessing the end product of a process than can be measured in years. What is invisible to us – the submerged evidence – is the countless hours of practice, the relentless drills, the mastery of technique and form, the solitary concentration that have literally altered anatomical and neurological structures of the master performer.
