It's a marvel.

Kids learn because they are full of curiosity and wonder. That's big. It's a marvel. Wondering is what takes people—including children—from observation to something else, to asking questions and looking for answers. To trying and finding out. Wondering is one of the reasons people push through challenges—climb real mountains and metaphorical ones. You can't Give someone that kind of motivation; it only comes from deep within. Sadly, you can take it away, and teaching someone who doesn't really want to be taught is a proven way of doing so.
