I'm a big believer in getting kids involved in things where there's a shared interest because that's where they can have friends.

One area of study that still needs to be done is the kind of autism where kids have speech and they lose it. Some parents say it's happened right after vaccines. That group needs to be studied separately from others.

Unfortunately, most people never observe the natural cycle of birth and death. They do not realize that for one living thing to survive, another living thing must die.

People can live up to high standards, but they can't live up to perfection.

I don't like the way most people think. It's imprecise. I find that when parents ask me questions, they ask very imprecise questions. They say, "My kid has behavioral problems at school." Well, I have to say, "What kind of problems? Is he hitting? Is he rude? Does he rock in class?" I need to narrow questions to specifics. I am very pragmatic and intellectual, not emotional. I do get great satisfaction when a parent says, "I read your book, and it really helped me."

My grandfather was an engineer who invented the automatic pilot for airplanes.

The world needs different kinds of minds to work together.
