How much dopamine you experience from something depends on your baseline level of dopamine when you arrive there and your previous dopamine peaks.

Thus, when you repeatedly engage in something you enjoy your threshold for enjoyment goes up and up and up.

• Dopamine is a neuromodulator – influences the communication of many neurons at once.
• There are 2 main neutral circuits used by dopamine to exert effects: (1) mesocortical limbic pathway – responsible for reward, motivation, craving; (2) nigrostriatal pathway

Dopamine is the primary determinant behind how excited we are, how motivated we are, and how ready we are to push through things to get what we want

• There is a baseline level of dopamine circulating in your brain and body all the time (important for how you feel generally) - tonic release of dopamine
• You can experience peaks dopamine above baseline - phasic release of dopamine

• The key is to not expect or chase high levels of dopamine when we participate in certain activities.
• Intermittent schedules can keep you motivated and engaged: make sure dopamine peaks don’t occur too often and vary how much dopamine you experience w...

• Cold water exposure can boost dopamine up to 2.5x above baseline – but is sustained for up to three hours post-exposure
• Dopamine controls the perception of time: when we engage in activity for the sole purpose of reward, time will feel longer because we are not relea...

• Mucuna pruriens contain L-dopa which is the precursor for dopamine– but the crash takes place
• L-tyrosine is an amino acid precursor to L-dopa; leads to a increase in dopamine and can improve focus but dosing is difficult to dial in and will be follow...
