The science here is psychology, and you're right, she is on a very good path toward understanding the human mind. Unfortunately, it is the least developed of the sciences, and therefore easily confounded. The progressives have confused science for political ends, but the evangelical right is worse. Regardless, the scientific method died in the West with the fall of Rome, if it had existed since Aristotle, and didn't become concrete until the Enlightenment.

All of that may be true, but I don't think its very helpful without an understanding of the concept of motivation. People who excel in math are able conceptualize, meaning integrate concepts into wider abstractions. The point of this short video is that can be learned. Regardless, motivation is a vague term and should be defined. To me, it comes from pride, which comes from productiveness, which comes from integrity, which comes from honesty, which comes from justice. However, these are not linear relationships, they are codependent virtues in a complex system known as an active and rational mind.
