I WAS sensitive when I was young. I was always this big kid. I had my first amateur fight at seven years old. I always had to fight older kids because none of the kids my age were as big as me. When people said stuff to me, it gave me motivation to succeed. I learned to block out the negativity.
Winning against Anthony Joshua [on Saturday June 1] would be awesome. My dream is to be the first Mexican heavyweight champion of the world. At one time, though, I wanted to give the sport up. I listened to the doubters who said that I was too big to be a champion. I was a big troublemaker when I was a kid at high school. I was a little gangster with a shaved head who was going around with the wrong cliques. I was hanging around with the wrong people and doing bad things. Thankfully, boxing kept me away from major trouble. Boxing saved my life.
I was six years old when my dad first took me to the gym. I got my ass kicked, so I didn’t want to go back. But my dad told me to keep going. Then, after only about a month, I started kicking their asses. My dad always believed in me. I wouldn’t be where I am today without him. When I was out on the streets with the wrong people, he’d come and find me and make me train. I started getting serious in the sport at about 15 or 16, when my dad took me to Mexico City.
