You can sail in the desert with a ship of fools. You can smuggle in Moses and his book of rules. But you can't take a mother and give her back her son. What kind of freedom is bought with a gun? People like to build their prison walls when they're afraid to look inside... a thousand points of light are the muzzle flashes in the night. And the freedoms you profess to hold won't bring the dead back from the cold.

I think the best way to find out about something is to try to do it to the max. A lot of people take up a hobby or sport and then find an excuse not to carry on with it. Once I start something, I won't stop until I'm as good at it as I'll ever be.

Engineering stimulates the mind. Kids get bored easily. They have got to get out and get their hands dirty: make things, dismantle things, fix things. When the schools can offer that, you'll have an engineer for life.

Well, yeah, sometimes I get a little too creative.

Nothing lasts forever but the certainty of change

My son is in a band, and he’s a singer, and his vocals … they’re screaming-growling stuff … and he’s got a pretty reasonable voice. Yet he practices really hard to get the screaming-growling thing without losing that voice every five minutes. So I’m, like, “Hats off to you.”

I guess that the salary that they get when they are working with me is, like, it beats working at McDonalds, so it has got some things going for it.
