I sing because I'm happy..

I don't write novels about expeditions to the planet Mars because I haven't been there and I don't know anything about it..

You never know what to expect. You don't just walk on and expect an amazing reaction..

Everything was invented when somebody was alone..

I'm discriminated against all the time..

I don't really see science fiction as fiction. I can imagine colonies on Mars and everything..

[I'm] more German than Irish..

I am at my best when I am scoring..

I never thought I was the best; I just thought I was one of the best..

I'm happy, but there's nothing to jump around about..

The work that I'm proudest of is the work that I'm most afraid of..

I never worked with a stinker. How great is that!.

I'm going to build a reactor, that's for sure..

I do what I like now. I just don't have time for it all..

Let us not go over the old ground but rather prepare for what is to come..

Do what you're doing while you're doing it..

Xxxx xxxx x xxxx, xxxxx xxx x xxx xxx x xxxx. Xxxx xxxx xxxx x xxxxx xxxx xx Xxxxxxx..

I fought for peace in the fifties..

You cannot kill what you did NOT create.

Any one in love will have no religion..

Those who are nurtured best, survive best..
