The Talent Code
by Daniel Coyle
Skill consists of identifying important elements and grouping them into a meaningful framework. The name psychologists use for such organization is chunking.
(1) talent requires deep practice; (2) deep practice requires vast amounts of energy; (3) primal cues trigger huge outpourings of energy.
The trick is to choose a goal just beyond your present abilities; to target the struggle. Thrashing blindly doesn't help. Reaching does.
