But it is a delightful challenge to try to depict interesting aliens.

My first duty to write a gripping yarn. Second is to convey credible characters who make you feel what they feel. Only third comes the idea.

We already live a very long time for mammals, getting three times as many heartbeats as a mouse or elephant. It never seems enough though, does it?

When it comes to privacy and accountability, people always demand the former for themselves and the latter for everyone else.

My education and background thoroughly inform my writing.

Anyone who wants simple, pat stories should buy another author's product. The real universe ain't that way, and neither are my fictive ones.

The worst mistake of first contact, made throughout history by individuals on both sides of every new encounter, has been the unfortunate habit of making assumptions. It often proved fatal.

It is said that power corrupts, but actually it's more true that power attracts the corruptible. The sane are usually attracted by other things than power.

I would normally never set out to write a trilogy.

But honestly, if you do a rigorous survey of my work, I'll bet you'll find that biology is a theme far more often than physical science.

In the book, America had already been weakened by bio terror plagues before waves of selfish violence took down the rest. But the real enemy was the kind of male human being who nurses fantasies of violent glory at the expense of his fellow citizens.

Why must conversions always come so late? Why do people always apologize to corpses?

Predicting has a spotty record in science fiction. I've had some failures. On the other hand, I also predicted the fall of the Berlin Wall and the rise of fundamentalist Islam... and I'm not happy to be right in all of those cases.

Above all, TRIBES is fun, and even kind of sexy... in that every round features an Opportunity for Reproduction, which is the main aim of the game, as it is in most of Nature.

Self-righteous people can talk themselves into forgetting they are part of a civilization. They can then feed on that culture, bringing it down. It's happened many times in the past. It could happen to us.

When I begin a book, I inevitably discover many things along the way, about the characters, their past histories and the political intrigues that surround them. This discovery process is vital, and I would not prejudice it by deciding too much in advance.

I find humans tremendously interesting.

Only a knowledgeable, empowered and vocal citizenry can perform well in democracy.

Fortunately, human beings are remarkably diverse models to work from.

There's no doubt that scientific training helps many authors to write better science fiction. And yet, several of the very best were English majors who could not parse a differential equation to save their lives.

I like to be surprised. Fresh implications and plot twists erupt as a story unfolds. Characters develop backgrounds, adding depth and feeling. Writing feels like exploring.

One of the rules I try to follow is that normal people are going to be involved even in heroic events.

But it is a delightful challenge to try to depict interesting aliens.

Change is the principal feature of our age and literature should explore how people deal with it. The best science fiction does that, head-on.

She had called in the debt that parents owe a child for bringing her, unasked, into a strange world. One should never make an offer without knowing full well what will happen if it is accepted.

Only people with full stomachs become environmentalists.

Self awareness is probably overrated. A complex, self regulating system doesn't need it in order to be successful, or even smart.

Roosevelt's magic lay in one facet of his personality: He knew how to take the risk. No other man in public life I knew could so readily take the challenge of the new.

To do the Ozzfest again would be great. I'd like to finish with a final Sabbath album. You always feel that it is still a challenge.

People are not perfect... very often the relationships that are strongest are those where people have worked through big crises, but they've had to work through them. So the challenge to us is to work through that.

Every single book is a challenge.

Critics are sentinels in the grand army of letters, stationed at the corners of newspapers and reviews, to challenge every new author.

The lopsided attitudes of college professors pose a serious challenge to learning because students are so susceptible to becoming lopsided sheep.

I really enjoy comedy. It's a real challenge.

I had a hard time with that hockey. I hadn't grown up skating, so that was my biggest challenge. We worked on it and worked on it. But then when we first shot it, it was so hard for me.

The challenge is to practice politics as the art of making what appears to be impossible, possible.

Change can either challenge or threaten us. Your beliefs pave your way to success or block you.

My greatest challenge has been to change the mindset of people. Mindsets play strange tricks on us. We see things the way our minds have instructed our eyes to see.

I'd say that it's important for music to be there that gives you a challenge, that rearranges things in your head.

I like good stories. Quality products and character are what's important. Even if the script isn't that strong, if I challenge myself with a great character, I'll go for it.

I tend to arrive in the rehearsal process with very strongly developed ideas about what I want to do. But I don't like those ideas to be things that are not subject to change, or subject to development, or subject to challenge.

I'm not looking to set a standard... but, I believe I have offered a challenge to others with my work.

If you live a life of make-believe, your life isn't worth anything until you do something that does challenge your reality. And to me, sailing the open ocean is a real challenge, because it's life or death.

And, I'd never done Tennessee Williams, and I had done Broadway musicals, so it was a challenge.

When you remove the risk, you remove the challenge. When you remove the challenge, you wither on the vine.

After Land I wanted to continue exploring the theme but I needed a new challenge so turned to colour. I explored Bradford and produced a series of urban landscapes that I liked, but because Land had made such an impact on the general public my colour work wasn't reviewed.

The worlds I paint leave a lot to engage the imagination by hinting at what lies beyond the four edges of the painting. I think getting beyond the four edges of an opportunity or challenge is one of the basic skills you need in business.

For me, it's a bigger challenge, it's much harder to do and much more rewarding to do well, then just to think up stuff of your own, hit or miss, because you've got to see to it that you don't torpedo any of his punch lines.

This same habitual blindness to spiritual, substantive dimensions of every significant challenge continues to handicap Hollywood.
