π Choose three or four habits to create and commit to doing at least four of them every day, without carrying over any missed habits to the next day.
π§ Understand the dopamine system and train your brain to receive random intermittent rewards for performing habits consistently, rather than rewarding yourself after completing a large task.
β° Consider the neuroscientific aspect of habit building and strategically place certain habits earlier or later in the day to optimize their effectiveness.
β° The day can be divided into two phases: zero to nine hours after waking and ten to sixteen or seventeen hours after waking.
π§ Linear habits, which are easily repeatable actions, are best suited for the first phase.
π‘ Non-linear brain operations, such as creative writing and brainstorming, are more effective during the second phase.
π Running linear versus non-linear and the importance of matching habits to the appropriate time of day.
π€ The significance of sleep in forming habits and the recommendation to align habit formation with the easiest times of the day.
π The role of time of day in performing different tasks, such as creative work, skill development, and goal setting.
π Fear is a more powerful motivator than positive thinking.
π Goal setting based on real-world fear is more effective than positive goals.
π Random intermittent rewards are a better way to stay motivated than constant rewards.
π‘ Making errors is essential for learning because it cues up the forebrain and increases activity in the prefrontal cortex.
π The optimal ratio of errors to successful trials for optimal learning is the 85-15 rule.
π― When we succeed, our nervous system relaxes, causing us to pay less attention to the next trial and hindering our learning.
π‘ Optimizing learning requires a difficulty level of about 15% error rate.
π Machine learning algorithms and animal data support the idea of an optimal difficulty level for learning.
π Internal rewards should be prioritized over external rewards in order to enhance motivation for training.
π Rewarding everyone diminishes the role of rewards and limits access to the reward system in the future.
π§ Depleting the dopamine system can lead to lack of motivation and depression, similar to Parkinson's disease.
