The most important aspect of your nervous system is action, because your thoughts and feelings are temporary, but your behaviors are the only thing that creates a fossil record of your existence.

Your ability to focus and learn operates in 90-minute "ultradian" cycles throughout the day, and you can optimize learning by structuring your efforts within these natural blocks of time.

Research shows that playing a simple tone in the background while learning a skill, and then replaying that same tone during deep sleep, significantly boosts learning and retention rates.

A study showed that performing 20 minutes of deep rest, or non-sleep deep rest (NSDR), immediately after a difficult learning session significantly accelerates neuroplasticity.

The actual rewiring and strengthening of neural connections does not happen while you are learning, but occurs during subsequent periods of sleep and non-sleep deep rest.

The feeling of agitation and strain when learning something difficult is the necessary entry point for neuroplasticity, signaling that your brain is ready to change.

Dopamine is more a molecule of motivation that drives you to pursue external goals, while serotonin is what makes you feel content with your current resources.

Humans can split their attention into two attentional "spotlights," contrary to popular belief, allowing focus on two separate things simultaneously.
