Don’t sit down in the middle of the woods. If you’re lost in the plot or blocked, retrace your steps to where you went wrong. Then take the other road. And/or change the person. Change the tense. Change the opening page.

Oh ya, I doubted more than expected. I had doubts all the time. The way was extremely, extremely difficult. … At one point I had to describe what I am doing to a person who is a great intellectual but not a scientist, and I told him what we felt is that we are climbing mountains in order to reach the climax – and these mountains are like the Everest, the biggest most difficult to climb – only to find out that there is another mountain waiting behind it to be climbed afterwards. So every climbing was an achievement but there was a bigger problem behind it or above it. I had lots of minutes that I didn't expect, but I thought science in general and this science particularly is worth the effort – even if we would never get the ultimate result.

When I was in Beijing, London, and also in Rio I was still a kid really, I didn't feel pressure. Now I'm a 26 year old woman. Being a lot older I feel those expectations. And it's definitely hard on my shoulders, to the extent where in training I'm ok but in competitions I panic, and I do stupid things. Working with [my psychologist], at these Games one of the things I'm proud of is I didn't have any panics. I was so happy about that - I went out and raced and enjoyed it.

The real problem is that the pain actually gets worse. You have created massive acidosis in your muscles so there is a huge quantity of hydrogen ions and the pH in your blood changes. For 15 minutes you lie there thinking, "God, this is really bad. I'm going to die. It has never been this bad before." And every time you think exactly the same thing. You have to lie to yourself by saying you're not doing a second set. Then, without moving for 15 minutes, almost to the second, I would roll over and think, "OK, I think I can do a second set now." During those sessions I have never felt more alive or so close to death.

I think it’s more modeling. I never bring in my children and say, “Listen, these are the values you should follow in life.” I think it’s a modeling by my wife and me. I think we give them a good life. They saw how we go through life: a difficult time, a hard time, good time. I am very happy. I think they are good kids. If I have hope, it’s because I look at my children.

Well, many. I think Steinbeck, for example, was one of my favorites, Somerset Maugham, Hemingway. Quite a few.

My sister-in-law and I are working towards the same goal, through different paths: the security of the human family.

No. Unfortunately, it hasn’t worked out quite that way. At that time, everybody was euphoric that we will have a new world order, you know, a world order that does not rely on nuclear weapons, nuclear deterrence. Unfortunately, it didn’t work that way. ... We still have thousands of warheads in existence. We still have more than 20 — 30 countries relying on nuclear deterrence for their own survival.

Unfortunately, in the case of Iraq, I believe we could have done that through an inspection process. I was calling for a few months more to complete our work. We hadn’t seen indications of weapons of mass destruction. We hadn’t seen indications of nuclear weapons. ... Unfortunately, it didn’t work that way. There was faulty intelligence. There were lots of other considerations that made a decision to go to war tempting, to get rid of Saddam Hussein.

For them, home is the world. For them, every human being is just one member of that large human family you have. ... if we have more children like mine, in my view, we will not have war.
