The secret to creativity is curiosity.
We often forget to teach kids to be curious. A student who has no perceived math ability, or illegible handwriting or the inability to sit still for five minutes gets immediate and escalating attention. The student with no curiosity, on the other hand, is no problem at all. Lumps are easily managed.
Same thing is true for most of the people we hire. We'd like them to follow instructions, not ask questions, not question the status quo.
Yet, without "why?" there can be no, "here's how to make it better."
