It may also be that it's not just the coffee for some of us. I have a whole ritual early in the morning around making my coffee. I grind the beans, put on the water to boil. And I brew the coffee in my French press. After I've had a couple of cups of coffee at the beginning of the day, I feel really good and ready to start my day. The expectation and enjoyment of that cup of coffee should be factored in.
