We all start at 0.

Can't talk, can't walk, certainly can't do algebra.

Adding, reading, writing, riding a bike, nobody's good at anything at first.

There was a time when Einstein couldn't count to 10, and Shakespeare had to learn his ABCs just like the rest of us.

Thankfully, we're born to learn.

Slowly, surely, you stumble, slip, crawl, fall, and fail, and fall.

Frustrating, confusing, trying, struggling…until one day, you walk.

One foot in front of the other, one idea on top the next, each wrong answer making your brain a little bit stronger.

Failing is just another word for growing, but you keep going.

This is learning.

Knowing that you'll get it even if you haven't gotten it yet.

Because the most beautiful, complex concepts in the whole universe are built on basic ideas that anyone, anywhere can understand.

Whoever you are, wherever you are, you only have to know one thing: You can learn anything.
