"Big business," Lesnar said. "At the end of the day, I'm a prize fighter. Listen, titles don't pay the bills. I'm a prize fighter, I fight for money. It's no different. They're making money, I'm making money, everybody's making money. That's what this is all about, but more importantly it's not about the money to me. I've always said money's very important to me, but you can't step inside the Octagon just for the money.
"This is in my heart. This is from the heart and it just so happens I'm making a boatload of money."
"I'm sitting here today, I feel 1,000 percent. I wouldn't get in the Octagon if I didn't," Lesnar said. "I'm not a second guesser. The only thing I second guessed was my decision of stepping away from the Octagon.
"I know it's been a long time, but I feel great. I don't have to fake it. I'm not faking and telling anybody that I'm in the greatest shape of my life or something like that. This is for real. This is for real and I'm so excited and I'm glad for my decision."
As far as the future goes, Lesnar can't say for sure that his desire to fight will be satiated with only one bout back in the UFC, but after the event on July 9 wraps, he's turning his attention back to the WWE.
"It may just be a tease but I don't know the answer to that question right now," Lesnar said about his future with the UFC. "We'll cross that road when we get there, but first and foremost, I've got a big event after this event, SummerSlam for the WWE so I'm a busy beaver."
