“how much dopamine is in our system at any one time compared to how much dopamine was in our system a few minutes ago, that dictates your so-called quality of life and your desire to pursue things. This is important. Your experience of life and your level of motivation and drive depends on how much dopamine you have relative to your recent experience. This is why when you repeatedly engage in something that you enjoy, your threshold for enjoyment goes up and up and up.”

“One way that you can ensure that that cortisol peak occurs early in the day, right about the time that you wake up, is to view bright light, ideally from sunlight, within the first 30 to 60 minutes after waking. The reason for that is very simple. You want to trigger that cortisol increase to occur very early in your day, and you don't want that cortisol peak to happen later, which is what will happen if you wait to get outside and see sunlight.”
