I don’t want my thoughts to die with me, I want to have done something. I’m not interested in power, or piles of money. I want to leave something behind. I want to make a positive contribution - know that my life has meaning.

I think one of the worst things schools have done is taken out all of the stuff like art, music, woodworking, sewing, cooking, welding, auto-shop. All these things you can turn into careers. How can you get interested in these careers if you don't try them on a little bit?

I get asked a lot why cats mess outside the litter box. The simplest thing is if you have more than one cat and you have two litter boxes, don't put them right next to each other.

You have to use food motivation whereas a dog will do things for you just for social motivation, praise and petting. Also with any animal you want to stroke it. Don't pat it, stroke it. Most don't like patting.

In an ideal world the scientist should find a method to prevent the most severe forms of autism but allow the milder forms to survive. After all, the really social people did not invent the first stone spear. It was probably invented by an Aspie who chipped away at rocks while the other people socialized around the campfire. Without autism traits we might still be living in caves.

There's no black and white dividing line between a mild Aspergers, which is the mild autism, and computer engineer, for example.
