“But when it
comes to learning, the science is clear: Exhaustion is the enemy. Fatigue slows
brains. It triggers errors, lessens concentration, and leads to shortcuts that
create bad habits. It’s no coincidence that most talent hotbeds put a premium
on practicing when people are fresh, usually in the morning, if possible. When
exhaustion creeps in, it’s time to quit.” –Daniel Coyle, The
Little Book of Talent: 52 Tips for Improving Your Skills
