My life is so active, and I'm fighting the whole day that I don't have any aggressiveness or any energy outside of fighting. I'm the most chill couch potato you could ever meet.

I always say you have to be willing to get your heart broken.

If there's a camera on me or off me, it's roughly the same, just a lot less energy.

I wasn't allowed to throw big hooks and overhand rights until I'd been striking for three years. It's so you don't rely on those things from the very beginning. If your footwork sucks, and you can only stand in one place and throw your hands all crazy while the other person is running around, you're never going to be able to hit them.

I never really liked weightlifting because there is no problem solving, whereas when I am fighting, I am trying to solve a problem, so I don't think about being tired. I box, wrestle, do jujitsu, run up sand dunes; every single day is something different so that I am mentally engaged. That's what makes me want to train longer.

I wasn't always the most fashionable, and I would come to school with cauliflower ear and ringworm. I got made fun of a lot. People called me 'Miss Man' and 'Guns,' and people directed a lot of karate jokes at me. I wish that I was at school now that MMA and martial arts is cool, but back when I was in school, people associated it with nerdy stuff.

I had a certificate that said, 'Doctor of Mixology, Harvard University,' that I actually got from Harvard University. A friend of mine was a research assistant over there and it was one of those student or university perks and she brought me in on that. So I am a doctorate from Harvard and it only took me one afternoon.

I've separated my shoulder and my collarbone; I've messed up my knee a million times. I've broken my foot in several places. I've broken my toe a bunch, broken my nose a couple of times, and had a bunch of other annoying little injuries, like turf toe and arthritis and tendonitis. It's part of the game.

I love feeling like I'm inhabiting the body of a ninja, like I could rob a liquor store with my bare hands if I wanted to.

I make fractals. They're like mathematical pictures. My stepdad is actually a rocket scientist, so in his free time, he gave me a fractal program for fun. He showed me how to use it when I was about nine or 10, and I made thousands of fractals.

The whole 'bad girl' thing allows me to mess up sometimes. And I have freedom to say more of what I want to.

Even if they don't know it, everyone has the instinct to survive.

When women say that going on publications directed at men is somehow demeaning, I don't think that's true. I think that's one really effective way to change the societal standard women are held to.

I don't lift weights at all. Every muscle on my body is for an actual task; there is no muscle that I train for show. If I want to be able to do a certain move or action, I train really hard until I can. And with all of that training comes muscle definition, so it's really an afterthought.

I only have so much ring time that my body can endure. I've had four surgeries on my knees, arthritis in my neck, separated my shoulders, broken my nose. I'm just gonna hope that science advances faster than I can deteriorate. Because what am I gonna do? Put a perfect body into the ground? What's the point of that?

I'm a terrible singer, but I'm not shy about it. I'm shy about dancing.

Where is women's sports prominently displayed with the men? Tennis is the only thing I can think of.

The Olympics is a once-in-a-lifetime thing. I was lucky enough to go twice, but most people only get one chance. And in judo you can train your whole life and it'll come down to a split second: You can lose everything or win anything.

I had a lot of trouble speaking as a kid. I didn't really speak in coherent sentences until I was, like, 6 years old. There was a long time where everybody was very worried, because my sisters were so advanced for their age, and I would barely talk.

People say this all the time and everyone, like, nods their head and is like, 'Oh yeah, totally,' but no one ever does it, including myself. I can do better at it, is just drinking a lot of water, like a gallon and a half, two gallons a day, like, straight water all day.

I have to be out there to sell these fights; it's not because I really enjoy getting made up and going to work every day. It's cool, it's an awesome job, but it's still a job. I'm doing it because it helps me make a living and not because I'm so extremely vain that I want to see my face everywhere.

It took a lot of time to develop a healthier relationship with food and with my weight.

Somehow, people act like I have no competition, but the thing is, the competition is so good that it forces me to be better than I even thought was possible.

Reality TV is set up to make people entertaining. A good person with values and principles is not good television.

To be honest, in 2012, I was against both candidates, and so I just picked any third party because I thought if more people voted for third parties then they'd have to take third parties seriously.

A lot of people, once they become champion, they relax, kind of sit in the position and try to enjoy it. But I feel like everything I've ever worked for could be lost at any moment. I work harder and harder and harder, because I want to be farther ahead with every fight, and not worrying about these girls catching up to me.

There's something so zen-like and grateful of just ripping a hot wing apart and getting it all over your face, and everyone's happy. I love that atmosphere.

I grew up as an athlete doing judo, so I didn't really have a conventional, feminine body type.

I go mainly by the Dolce diet. It is a little hard to describe: it's not really a diet but more of a lifestyle. I eat throughout the day; I have three meals and two snacks, and it changes according to what I need at the time.

I lost a lot of judo matches because of points fighters. It was extremely frustrating for me.

I love Canadians. They are the coolest, nicest, most patriotic people, and they will support their countrymen no matter what, and I think that's commendable.

I think that going on any reality show is not good for your mental health because you behave differently when you are being watched, and you constantly have an extra bit of awareness of what's going on all the time.

Being an athlete, you try to get protein.

Look at my face. Does it look like I can take a good hit?

If I could have had everything exactly the way I wanted, this is how I would have written it down. Win all my fights in the first round, then go to the UFC and headline a show, and have it as a pay-per-view and at home. People's dreams don't come true like that.

At home, I watch fights and documentaries - that's it. If it's not about the birth and death of stars, 'Frozen Planet,' or someone getting punched in the face, I'm probably not watching it.

For me, MMA is like speed chess. It's like I'm herding a person into a certain position. Say my endgame is an arm bar. I'm not gonna actually take you and put you there. What I'm going to do is convince you that it's a good idea to move in the direction I want you to go.

I respect Georges St. Pierre as a businessman and an athlete. I don't have anything against him personally. But he's not the kind of fighter I like watching.

I don't shy away from any questions. I'm not scared of any question. I'll give you an answer. A lot of people are scared of having actual opinions out there. People are so scared of criticism... I'm not scared of people disliking me.

Most people get scared away from having an opinion. It's not so much my opinions everybody relates to, it's that I don't care about being punished for it.

It's not my responsibility to make everything I say idiot-proof.

People can say I am a terrible role model because I swear all the time or that I fight people. Look, I don't want little girls to have the same ambitions as me. I want them to know that it is O.K. to be ambitious. I want them to know that it is O.K. to say whatever it is that is on their mind.

Believe me, there's nothing I would like to do more than disappear for a while.

I'm selling a product, and I have to be out there; I don't have the option not to be.

What I'm really looking to do is retire undefeated; I'm not sure when the right time to retire will be, but I know that I'm not done yet. Something still feels unfinished, and that's why I'm going to keep going.

A lot of my best clothes I buy at photo shoots because I don't have time to shop.

I like to be part of the change I want to see in the world. Not being afraid of criticism is actually a big advantage.

I'm the champion because I'm the best in every area.

I was just a little three-year-old kid, and I loved Hulk Hogan. And when you're a three-year-old kid, you don't list off the reasons. I was just drawn to him. He was always my favorite, even in the video games and everything like that. He was the one that I always remembered and liked the most.

Mine's going to be the best book tour that ever happened!
