When you're doing that exercise, it's not as if your nervous system thinks you're actually performing that behavior. Your nervous system isn't stupid. It's actually a lot smarter than that. It knows the difference between a thought and an action, but when you do that, it sets in motion the same neurons that are going to be required for the execution of that habit. And so when you actually show up to perform that habit, it's as if the dominoes fall more easily. It's a lower threshold, as we say, in order to get the habit to perform.
