This episode explains the science of motivation and drive. I describe how dopamine, a chemical we all make in our brain, underlies our desire for and pursuit of our goals, as well as our capacity to move and experience pleasure. I describe how we can leverage specific behaviors, reward schedules and dopamine-prolactin balance to help ensure we can maintain motivation and capacity for pleasure over the long term. I also discuss dopamine in the context of ADHD, craving and addiction, and some absolutely amazing results about specificity of drug effects based purely on belief.
