For deliberate practice to work, the demands have to be serious and sustained. Simply playing lots of chess or soccer or golf isn't enough. ... It requires constant self-critique, a pathological restlessness, a passion to aim consistently just beyond one's capability so that daily disappointment and failure is actually desired, and a never-ending resolve to dust oneself off and try again and again.Deliberate practice is defined as a quest for failure. Does this translate into a rationale for an obsession with blitz when one is playing badly? Perhaps the critical question should be posed another way.
