年轻
The only phrase I've ever disliked is, 'Why, we've always done it that way.' I always tell young people, 'Go ahead and do it. You can always apologize later.'
"I am not young enough to know everything."
I was so much older then, I'm younger than that now.
I think it's important to have a good hard failure when you're young... I learned a lot from that. Because it makes you kind of aware of what can happen to you. Because of it, I've never had any fear in my whole life when we've been near collapse and so on. I've never been afraid.
The art of teaching consists in large part of the ability to awaken the natural curiosity of young minds and to satisfy it with the nourishment of knowledge.
The heart of the educator must be a living flame, a fire that can ignite the souls of the young.
