As a child, you want to learn things that you believe will help you improve upon or allow you to do something that you want to do. Learning with that internal craving becomes habit forming.

Education becomes a practice of memorization without relative goals—that seed of your desire to learn. The goal can be to simply obtain a better understanding of a subject, but to understand, you have to want to understand.
