If I wake up one day and people tell me I'm not sexy, I'm not going to stop making good music and having fun. That 'sex symbol' thing is typically part of being in the limelight. You better be very talented in your music, but it's good to be nice to look at, I guess.

When you look into the eyes of your people out there that came to see you, that's when it's like, 'Yep, this is what it's all about.' This is why we don't sleep, and this is why we write songs and try to be the best. This moment right here onstage.

Just really, really believe in what you're trying to do. Don't let people alter that. Let people advise you and lead you down paths to make smart business decisions. But trust your instinct and trust that overwhelming drive that made you put all your dreams and everything on the line.

It's pretty cool to see how far music can take you.

You never take your fans for granted. You always appreciate them every show, night in, night out.

My first memories of music were country music and Ronnie Milsap. Where I grew up, it was what you listened to. And anything else, you were somewhat out of place.

With every album, the approach is find the best songs you can find, write the best songs you can write and try to sound better.

We're putting on a show, and if I'm dancing and having fun, you can take a shot of the crowd, and they've got smiles glued to their faces.

It's kind of like a college degree... when you get one, no one can take it from you. When you get to say for the rest of your life that you've got a platinum album, that really means something.

I don't think you should write a book until you tell the absolute truth. You can't do that until you're 85, and I don't want to live that long. I've always prided myself on knowing when to get off, and I hope it works out that way.

I'm not sure that I want to be without some lack of confidence. If you are too sure of yourself, you don't grow. You may feel confident in some things, but other fields come up as a challenge. And if you don't anticipate trouble, you will be in trouble.

The more things you do, the more you can do.

If you want something done, ask a busy person to do it. The more things you do, the more you can do.

You see much more of your children once they leave home.

I think knowing what you cannot do is more important than knowing what you can.

I will never do another TV series. It couldn't top I Love Lucy, and I'd be foolish to try. In this business, you have to know when to get off.

You spell Bob Hope C-L-A-S-S.

Love yourself first and everything else falls into line. You really have to love yourself to get anything done in this world.

People either have comedy or they don't. You can't teach it to them.

It's a helluva start, being able to recognize what makes you happy.

You know what it would just be amazing to be remembered, you know like a mum telling a daughter ‘the boyband of my time, One Direction, they just had fun and they’re just normal guys but terrible, terrible dancers.’

If you want to do something, go for it -you've got nothing to lose.

You can lay in bed and think you don't stand a chance, that's what all of us thought, and here we are. We ended up doing all right.

Always be nice to people. Whatever how bad they are to you. To show them you are not like them.
