Many top professional sportsmen from different sports see a psychologist.

I don't think I'll be fighting when I'm 40.

There have been many boxing comebacks over the years, and sadly many of them do not have a happy ending.

Some fighters had blinding speed and reflexes in their heyday but faded badly with age.

I've won titles at home, I've won them abroad, I've defended titles abroad and lost them, and gone on to dominate my next opponent to win them back.

My final fight was called 'Unfinished Business' - and I finished it.

The general public don't like boxers. They prefer tennis players.

I'm not in this for superstardom. I do it purely for the love of the sport. I just love fighting.

I don't feel any remorse or guilt after a fight. I can sympathise with an opponent who is getting a beating, but if it is the choice between him and me, it's not gonna be me.

I did it the hard way, I fought everyone I could and I would not have it any other way.

People can look at my style and my faults, point out all the things I didn't do as well as other fighters but I was never knocked out or stopped.

I absolutely love boxing. I live and breathe it.

I've been in the ring. I've fought in a title fight. I know what it is like to lose a fight. I know everything a fighter has been through.

I don't tell lies. I don't need to.

I wear my heart on my sleeve and tell you how it is.

Boxing is a hurt game if you can't be at your best, can't be 100 per cent mentally and physically switched on to performing, to win titles, defend titles, defend yourself in the correct fashion, then I don't think you should fight.

I've always been into sport, I watch all sport - I love golf, tennis, football and to me to box and have people in the arena cheering me on, I'll always miss that.

The only thing I miss is the actual fight night and the feeling of winning. I can say this with my hand on my heart, there is no greater feeling than standing victorious in the ring or in the case of my last fight, a stadium.

I've even fought with a broken hand, against Brian Magee.

When I won the title against Jean Pascal it also won me fight of the year.

It's questionable whether I believe in God or Jesus but I do believe in a spiritual world and some kind of afterlife.

I believe my grandma is watching over me and I draw strength from that.

I would have loved to have fought 15-rounders, because I always come on strong at the end.

As tired as I am, I can always go another round, and I feel the other guy can't.

While I can fight, I will fight. When I can't walk straight or my hands are knackered, then you've got to turn it in.

I'd love to box in Las Vegas - it's the fight capital in the world.

You are never going to top boxing at Wembley stadium.

I look back at the first Groves fight, and it was all so bad, so wrong. Everyone was telling me it was going to be easy, the bookies, everyone. Like an unprofessional fool, like an idiot, I listened to them. I didn't give myself the best possible chance.

There's weaknesses in every fighter.

You are either genetically tough or you're not.

I always like to get that finishing blow and satisfy the crowd.

The fans want to see a conclusive finish. It's quite a brutal, barbaric sport and the people who watch it want to see someone out. That's what I do for a living.

My Smiths, my Carters, the Cashes - everybody embraced me and held my arms up when I couldn't do it myself.

I'm kind of a perfectionist about my songwriting. If I don't mean it, I don't think it's any good.

I've had a few ditty hits.

I moved back to Tennessee in '86 or '87. That's when I worked with the Carter Family because I really wanted to understand my roots.

Lots of girls marry at 16 in Tennessee.

There was a period where I was a little scared that I'd blown my chance.

I've matured as a writer and human being. I've got some wisdom under my belt.

I do feel I'm responsible to carrying on the music. That's what I was charged with as a kid. When I was a little girl, I was told, 'When we are gone' - when you're a kid, you never think they'll ever be gone - 'you have to keep the music alive, the Carter Family songs, and add your own songs.'

I'm really about my family and really proud of being a Carter.

I was thinking about it: so many of my stories are about my family life, not about being related to a lot of famous people. That's my grandma, that's my mama, my daddy, my aunt, my uncle, my stepdaddy. I'd probably tell them even if they weren't well known.

I started playing piano when I was 6, ukulele at 7.

I always wanted to be the rockin'est country chick in the universe.

If someone gets married at 15, they're either dumb or pregnant. I was both.

I'm pretty much an open book.

My songs are about who I am.

I've always had wanderlust to try and do different things, but I always return to the music of the Carter family.

There are no rules when it comes to songwriting, so I'd turn Carter family songs from the 1930s into pop songs.

If someone asked me to do something I didn't want to do or didn't think was right, I wouldn't do it.
