If you ever get a second chance in life for something, you've got to go all the way.

I have been dealing with claims that I cheated and had an unfair advantage in winning my seven Tours since 1999.

The unwillingness to accept anything short of victory, that underlying fury, is the fundamental building block of my bottomless motivation to succeed. It is my credo in all that I do in life from battling cancer to bicycle racing.

Live strong is exactly I guess what it says. It's one thing to live, but it's another thing to live strong, to attack the day and attack your life with a whole new attitude. This was a gift for me. I guess before the illness I just lived. Now, after the illness, I live strong.

Obviously, I come from one background, and the people that design fitness equipment have been doing it for years and years, and they know what works and doesn't work.

Hard work, sacrifice and focus will never show up in tests.

That was my decision, so I have to be responsible for that. It was one of the biggest mistakes of my life and I don't have a good reason for why I wanted to come back, I don't have a good reason for doing it all.
