Only one small thing separates top-performing students in the world from everybody else. 

It’s not how much they study. 

It’s not some enhanced genetic capacity for memorization.

It’s not even anything to do with their literacy or environment, although I think it’s safe to say those contribute.

The one thing that all top-performers do that others don’t is ask questions. Specifically, they ask Google.

Anytime they don’t know something, they find out immediately.

No “Oh, that’s weird.”

No, “I wonder why that is?”

No, “I don’t know.”

Just a perpetual, “Let’s find out.”
