To optimize learning and stimulate brain plasticity, it is appropriate to follow an active process: maintain a state of wakefulness and alertness, focus your attention intensely, and accept the mental agitation caused by your own errors, because these are what signal to the brain that it needs to adapt.

The idea that learning requires a state of wakefulness and focused attention is widely supported by cognitive neuroscience. A study published in *Nature Neuroscience* (mechanistic evidence) further demonstrates the key role of acetylcholine in helping the brain process… The full read →
