- Dopamine produces all ranges of emotions.
- Dopamine fires before the event occurs.
- If dopamine fires for teh wrong reasons, one would feel upset.
- Dopamine works in generating patterns based on experience.
- “Nothing focuses teh mind like surprise”.
- The ACC (anterior cingulate cortext) sends the error-related negativity electrical signal saying something is wrong.
- The ACC signal is changed to somatic signal for the muscles to interpret to say something urgent is happening.
- The ACC constantly updates and changes short-term thigns into long-term lessons

- Dopamine molecures have to be constantly trained and exercised in order for them to be the best.
- TD-Gammon studied its errors.
- The more quality practice & study of errors, the better.
- Kids aren’t rewarded for trying hard, they are rewareded for innate intelligence. This causes them to see mistakes not as a learning tool, but a sign of stupidity.
- “When we praise children for their intelligence, we tell them that this is the name of the game: Look smart, don’t risk making mistakes”
