Success sometimes can really bite you in the shorts.

• I got fitter when I did 'Joseph and the Amazing Technicolor Dreamcoat.' I wore a loincloth - that's a lot of motivation!
• Of course this is Vegas and it is the melting pot for all over the world, but people from all over the world know Donny and Marie. It is amazing. I have been in the business a long time to realize careers can be fleeting. Five years is a long career nowadays for some people, and here we are still going strong after 40 years.
• My father instilled in me the attitude of prevailing. If there's a challenge, go for it. If there's a wall to break down, break it down.
• I could play it safe by recording songs that are familiar, but am I expanding myself as an artist by doing covers? It's a catch-22. It's called show business: The word 'business' is in it, and you've got to be a businessman. But then again, you have to be true to yourself as an artist.
• It's a lot of work to keep reinventing yourself and coming up with new stuff, but that's what it takes to be in show business.
• A belief in God is vitally important, not just in show business, but stability in life. You know, to recognize deity is the most important thing that you can do. I mean, it comes to the Ten Commandments. They weren't ten suggestions. They were Ten Commandments.
• Of course this is Vegas and it is the melting pot for all over the world, but people from all over the world know Donny and Marie. It is amazing. I have been in the business a long time to realize careers can be fleeting. Five years is a long career nowadays for some people, and here we are still going strong after 40 years.
• I was never considered cool throughout my teens: a very important time to be accepted by someone, especially your peers. Yes, I had all the screaming women, but the guys hated my guts.
• Maybe I am a little bit guilty of trying to convince myself that I am cool to this point - even today. But I am so much more healthy than I used to be in my twenties, because I was not accepted at all.
• I believe in the institution of marriage. Of course being a Mormon, we believe in eternity rather than just till death do us part. If you really try hard, if you make it work, it's blissful. But I also know a marriage that isn't working can be painful.
