In a professional kitchen, the idea is to have your cooks not moving much while they're cooking. You want them to stay in the same spot.

I am not a picture guy. I like to live in the present and keep the image of the past vivid in my mind. I don't need the precision of the picture.

You don't become a chef to become famous.

It's a very naive idea to think that the chef is cooking everything, and, on top of it, is irreplaceable. That would mean that basically he is the only genius, and there are idiots all around him, which doesn't make sense.

Mindsets, skills and leadership, experience and access, and critical consciousness - we need all four of these things for our students to be the leaders, people and citizens we want them to be.

Domestically, a lot of people think Xi Jinping is becoming Mao Zedong. By giving Hong Kong democracy, people would look at them as enlightened leaders.
