I will tell you what, the Rock was my nemesis. We did enough for each other; we put each other over to be famous. If we didn't have that feud with each other, we wouldn't have had the success we both had in pro wrestling. We really did build each other. I'm very thankful we had those opportunities and those matches.

Innovation in an existing company is not just the sum of great technology, key acquisitions, or smart people. Corporate innovation needs a culture that matches and supports it.

Who have I picked fights with over the years? Bill Gates. Google. Mark Zuckerberg. Even - despite everything that's written about my relationship with Steve Jobs - we had yelling matches.

A utility can handle up to 20% of production from solar and that helps the grid because it produces electricity when needed. Solar power peaks in the middle of the day and that's also when air conditioning is running and businesses are operating, so power production matches usage.

It's important that I stay positive in my messages during matches because the rest of the team is following the tone and tension in my voice. Nothing in my voice should let them down.

I feel like I play better when I'm calm. There is an inner peace I can tap into sometimes during my matches.

Before I play matches I'm always switching myself on. That's why I have that walk-on music - Two Steps From Hell - they produce really good motivational gladiator-style music. As soon as that music comes on I'm switched on and I'm ready for a brawl!

Almost every morning when I go to the studio to work, I discover a fresh rose in the bud vase on my dressing table... one living and vital thing in a dusty arena of powder and tissue and matches and greasepaint.

Growing up watching WWE, they used to have bra-and-panties matches or pillow fights, and that's why my mom didn't want me to watch wrestling. But when my parents divorced, I was able to watch wrestling again, and that's when I started to really get into wrestlers like Ivory.

I wanted to be the best street fighter in Houston, Texas. And I thought if I got a trophy or two, I'd go back home, and everyone would be afraid of me. I had one fight in '67, the first one. In '68 of October, I was an Olympic gold-medalist, a dream come true, with a total of 25 boxing matches.

I remember the '70s constantly being winter in Manchester and the Irish community in Manchester closing ranks because of the IRA bombings in Birmingham and Manchester, and you know the bin-workers' strike, all wrapped up in it... They were violent times. Violence at home and violence at football matches.

If you were asked to go on 'Mastermind,' what would your specialist subject be? I wouldn't have a clue what I could answer questions on. Birmingham City Football Club would be a start, I suppose, but with a hundred odd years of history, thousands of matches, players and incidents to recall, even access to Google would leave me struggling.

My greatest point is my persistence. I never give up in a match. However down I am, I fight until the last ball. My list of matches shows that I have turned a great many so-called irretrievable defeats into victories.

I used to wear sleeveless T-shirts all the time on court, but now I've got a brand new look - I've moved on to polo shirts. Sleeveless T-shirts give you real freedom of movement and they keep you cooler in matches, but I just thought it was time for a change.

No one would ever take Messi out of a match if the teams are evenly matched. But it can be done in matches where we take a big lead. This way, he can preserve his fitness.

When you don't play, you really feel the difference of what matches give you. The match-sharpness, the fitness. It's what you need to progress.

In my view, fitness training isn't that important in England, as they all train with such intensity anyway and have a competitive edge when just sprinting. The matches are all hard-fought, too.

Every day, I get up to hit the gym; the schedule is such that it gives me the requisite energy to last the entire day. I stress on cardiovascular exercises, and the workout is programmed with my sporting schedule. Most of the fitness schedule is based on what I require for my upcoming matches.

I think the more matches that I play, the better shape I'm going to get in. That's the best type of fitness you can do.

Mental strength is really important because you either win or lose in your mind. And I'm not solely talking about sporting matches, boxing events - anything you do, you do it first with your mental strength. And you can actually train and develop it, and I am responsible for what I'm saying because I have experience with that.

As I got older and started moving up the ranking, the matches got more important, and my emotions ratcheted up. I guess I hid my real feelings behind the anger.

I always say that I need competition, and I need competition every week, and in Spain, I was at an amazing club, but I had four matches a year: Barcelona v Real Madrid, Real Madrid v Barcelona, and after that, we'd win 4-0, 5-0, 4-1, 6-1.

I've been lucky, my wife's been amazing. Any time we've had cricket matches she sends me to the spare room to get some sleep. She takes care of everything.

I want to be known as A.J. Styles, the WWE Superstar that he is, and have amazing matches, make memories - I think that's the goal.
