Long-term motivation for health-related behaviors can come from different sources. Behavioral scientists are still trying to work out how these sources fit together. For example, I go running nearly every day and have done so for 30+ years. How and why have I maintained this pattern? Daniel Kahnemann would suggest that dual motivational systems are at play: a system 1 that deals with instincts and emotions, and a system 2 that is deliberative and conscious. He might argue that system 2 prompts me to run because I am aware of the health benefits of exercise. On the other hand, Ed Deci might suggest that I am intrinsically motivated to run and do it because it aligns with my values and self and because I enjoy it.
