So it's like starting over again, but I look forward to the challenge.

I figured my body always would be able to repair itself. I think all of us believe that - until you begin to age and get hit with deteriorating joints.

I have done a series in the '60s, '70s and '80s.

I have twin boys, 12, and a daughter, 17.

I think I've got one more series in me, and I don't care what it is.

It's being in the right place at the right time and taking advantage of your opportunities.

I started out wanting to coach football.

Doing a series, every week you work with a new star.

I learn the whole script before I show up.

I've never minded my kids watching any of the series I did. That's important to me.

The Six Million Dollar Man was one thing, but I wanted to keep my own parts.

And about in the late '80s, I got kind of burned out a little bit.

I got kind of burned out, so I moved to Florida. I was down there for 10 or 12 years, raising children.

My fiancee and I recently eloped. We went on a fabulous honeymoon to Europe, and I was able to see and do everything I wanted without worrying about taking it easy.

I'm from Middlesboro, Ky., a little town on the Tennessee and Virginia border.

Acting is a tough business, and the percentage of people who make it is very low - it's about 1 percent.

I did a few more plays, and then I went to L.A., because I knew I could get a coaching job there.

I had no idea how big the show was at the time we were doing it because I was always working.

But I was still hoping to be able to coach and teach.

I've had disappointments and heartbreaks and setbacks and roles I didn't get, but something always came along that either made me better or was an even better role.

Then I got a bad back injury, and they thought I wasn't going to have any feeling in my legs.

So it's like starting over again, but I look forward to the challenge.

Knee replacement is serious stuff. And it actually could have made me worse.

I worked for the recreation and parks department for a year.

I thought I'd gone to heaven, because I grew up watching Roy and Gene Autry.

Even when I was young, playing college football, and I injured my knee, I bounced right back.

For 40 years, I put my body through a tremendous amount of work.

I just turned 66, and I'm starting to work again.

I've never seen a schedule where you just go in two hours almost every day of the week and then all day on one day. Then you shoot it at night with an audience and you're out of there.

Roosevelt's magic lay in one facet of his personality: He knew how to take the risk. No other man in public life I knew could so readily take the challenge of the new.

To do the Ozzfest again would be great. I'd like to finish with a final Sabbath album. You always feel that it is still a challenge.

People are not perfect... very often the relationships that are strongest are those where people have worked through big crises, but they've had to work through them. So the challenge to us is to work through that.

Every single book is a challenge.

Critics are sentinels in the grand army of letters, stationed at the corners of newspapers and reviews, to challenge every new author.

The lopsided attitudes of college professors pose a serious challenge to learning because students are so susceptible to becoming lopsided sheep.

I really enjoy comedy. It's a real challenge.

I had a hard time with that hockey. I hadn't grown up skating, so that was my biggest challenge. We worked on it and worked on it. But then when we first shot it, it was so hard for me.

The challenge is to practice politics as the art of making what appears to be impossible, possible.

Change can either challenge or threaten us. Your beliefs pave your way to success or block you.

My greatest challenge has been to change the mindset of people. Mindsets play strange tricks on us. We see things the way our minds have instructed our eyes to see.

I'd say that it's important for music to be there that gives you a challenge, that rearranges things in your head.

I like good stories. Quality products and character are what's important. Even if the script isn't that strong, if I challenge myself with a great character, I'll go for it.

I tend to arrive in the rehearsal process with very strongly developed ideas about what I want to do. But I don't like those ideas to be things that are not subject to change, or subject to development, or subject to challenge.

I'm not looking to set a standard... but, I believe I have offered a challenge to others with my work.

If you live a life of make-believe, your life isn't worth anything until you do something that does challenge your reality. And to me, sailing the open ocean is a real challenge, because it's life or death.

And, I'd never done Tennessee Williams, and I had done Broadway musicals, so it was a challenge.

When you remove the risk, you remove the challenge. When you remove the challenge, you wither on the vine.

After Land I wanted to continue exploring the theme but I needed a new challenge so turned to colour. I explored Bradford and produced a series of urban landscapes that I liked, but because Land had made such an impact on the general public my colour work wasn't reviewed.

The worlds I paint leave a lot to engage the imagination by hinting at what lies beyond the four edges of the painting. I think getting beyond the four edges of an opportunity or challenge is one of the basic skills you need in business.
