"I'm just the undisputed champion - I am great as I think I am and I've been able to prove it by taking on these big challenges and beating these girls who they say cannot be beaten."
"I grew up on North Saginaw, the north side of Flint, which is considered the worst part and I was able to make it; I was able to make it by just making smart decisions from a very young age."
"I tell all kids and the girls growing up that you control your own life, you control your destiny - not where you're born, not who your parents are."
"Flint is not a hopeless city and I mean that."
"When I was 16, coming up through now at 24, it was so much I thought I had to change about myself. Especially after I won the Olympics."
"I have a healthy respect. The fact that I get ready for each opponent shows my respect."
"A woman can beat me the day I stop working hard. I work so hard in the gym, it would be stupid of me to doubt myself. For me, I know that I'm unbeatable. You can put me in there with whoever."
"Confident is believing in yourself. Being humble is, even though you believe in yourself and you know what you're capable of, you still work 10 times harder than your opponent to make sure you get the output you want."
"I got the nickname T-Rex when I was 11 years old. Back when I was younger, I was very skinny and I had short arms, but I used to always be swinging."
"Boxing gave me self-confidence that I didn't have growing up. When I was young, I was super quiet and I didn't trust anybody. I didn't like having friends."
"Living in Flint, poverty is an obstacle that you have to fight through. I always had to fend for my brother and sister - I was always the one to sacrifice my meals so that they could eat."
"Can't nobody else get in there and help you. Your coach, he can't get in the ring and fight with you. You don't have your dad, your mom. When you get in the ring, you don't have anybody but yourself."
"The biggest motivation for me is becoming a three-division world champion faster than any other boxer, male or female."
"At the end of the day, I am the cash cow in women's boxing."
"I'm carrying the sport of women's boxing and I am the best woman fighter and that's my role."
"At the end of the day, no matter what you do, there will be somebody that don't like you. You don't have to like me, but you will respect what I do."
"The only thing that me and Muhammad Ali have in common is that we are both Olympic gold medalists and both very outspoken."
"My coach never looked at me as a female fighter, but just as a fighter, as someone he was training. I had to work just as hard as the guys, or harder than them."
"I was angry because I see other kids with things that I wanted: they had good parents, they had clothes, they always had food and extra money, and I wasn't one of those kids."
"I always tell my story because I want others who have felt broken to know they can make it."
"To be honest, I already felt that I was going to win the gold medal, but with school being so hard I was kind of second-guessing myself. So, when I actually was told that I was going to be able to walk across the stage and be done with high school, it was such a relief."
"I get recognized at the airport and at the malls in Colorado."
"I sign a lot of autographs and take a lot of pictures. That's why I've always got to keep my hair done now."
"Coming back to Flint and seeing my family keeps me humble. Even though I've been on a worldwide stage, I can still communicate with them on a hood level, if that's what you want to call it."
