A lot of people make the error of thinking rugby is going to last forever and they need to quickly discover that that isn't the case.

In reality, rugby is finite and unpredictable, so players need to have skills off the pitch too.

When I was about 15, I learnt that training hard doesn't get easier, you just learn to push harder. That's a powerful mentality to master.

When I started my professional rugby career, in 2002, there was one guy filming training if you were lucky.

I think 5G is going to make a dramatic difference in sport and beyond.

In rugby I think it is good to have a bit of a persona, a bit of a character because we are one of the last things that isn't necessarily controlled.

It was so important to have stuff outside of rugby so you have a life balance. I took a lot of criticism for that earlier in my career and thank God I ignored what everyone else said and did what I was always going to do.

I was diagnosed with ADD when I was 14. Weirdly enough, I then learnt, through doing different things, to concentrate.

When I am doing something I give it 100 per cent. I work on it, do it and go onto the next thing.

Do I respect my competition? Yeah. Do I always think that I could do a better job? Of course.

I'm always pretty fair-handed.

I like to think I am honest and open.

I like my boxing and jiu jitsu and that kind of stuff and one thing I always enjoyed from an early age was shooting. My godfather got me into it. It started with airguns and shotguns and that kind of stuff.

Shooting's not actually a bad place to take a girl on a date, unbelievably.

If you get an opportunity to win any silverware you take it.

Going to a final and winning is the best thing in life, and it makes rugby no longer a job. It makes it fun.

The best players aren't necessarily the biggest.

At some point, the power side of the game has to peak, players can't get much bigger. Guys will be doing more footwork and explosive-speed stuff.

In order to pack on the most amount of muscle from your training, you need to train specifically for hypertrophy.

Good nutrition must be at the core of all that you do training and health wise.

Although the TV commercials will try and have you believe otherwise, there is nothing good about breakfast cereal. No matter how 'low fat' or 'high in fibre' the box tells you it is, ditching the high sugar cereals is the first step you need to take towards a better breakfast.

I'm all about helping people understand more about exercise in general and more specifically on occasion, about certain key parts of their body and physique.

Front squats and trap bar deadlifts are the two best big compound movements for quad growth.

As a gambler, I hold myself to an especially high standard of honor, and it disgusts me when people try to cheat at games.

When I watched 'Jeopardy!' as a kid, I would primarily watch with my grandmother. She was the most beautiful person the world has ever seen. Her first language wasn't English, so she couldn't follow along well, but she wanted to share this experience with me since she saw it was something I really liked.

Nobody likes to lose.

Anytime you learn something new, you're just trying to file it away - might be useful one day.

My source of income is sports betting. I have some investments also.

In gambling we say you are 'on tilt' when your mood gets in the way of making your best decisions. And nobody plays well on tilt.

Easily the hardest 'Jeopardy!' categories to study in the kids' section are the so-called 'trashy' pop culture ones.

Like Dave Mustaine, I ain't superstitious.

There were times in school where I would say, 'I should go to class.' But I could make $100 playing online poker if I didn't go.

I spent almost no time studying categories like geography and sports, even though they came up frequently on 'Jeopardy,' because I'm already strong in those subjects.

I'm a pro sports gambler. You have winning days and you have losing days. But you know if you've got the right strategy, you're going to get it in the end.

I've already begun giving to children's nonprofits in the Las Vegas area.

It definitely helps that I can bet big with ice water in my veins.

I really like not having to justify my decisions to anyone else, as well as the freedom to vacation whenever I want.

I went to Illinois. Most people think I went to Princeton or something. But I was never a diligent student.

Parenting is much more nerve-wracking than 'Jeopardy!'

I think the best way to quickly describe my personality is that I'm a maximizer rather than a satisficer, i.e. I want to squeeze every drop out of an opportunity rather than settle for 'good enough.'

There are big advantages to having a lot of chips early on in a poker tournament. You can make plays that other people can't.

I know life goes on if you make a big bet and you lose. But if you don't give yourself the best chance of winning, you're going to kick yourself tomorrow.

I kind of didn't look at anyone else's strategy for 'Jeopardy!' I thought, I'm going to build this from the ground up... If I had never seen a 'Jeopardy!' game played before, what would I have to do to play it to maximize my winnings, maximize my chances of winning?

When I was a kid, I would turn on the television as soon as I got home from school.

As a sports fan, I like the one-and-done playoff setups of the NFL and NCAA, but a best-of-seven gives the favorite a much better chance of prevailing in the end.

It is exciting for me to see the stats guys winning the battle and getting into MLB front offices.

I bet sports all the time and very rarely get in a spot where someone offered me even money on something I'm going to get right five out of six times.

If you believe in yourself, you don't have to do things the same way everyone else is doing it.

There's nothing better for my interests and talents than combining math and sports for profit.

I want to not lose what makes me be me.
