"I won't predict anything historic. But nothing is impossible."
"I've missed more than 9000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed."Michael Phelps on Michael Jordan
"It's good sportsmanship to not pick up lost golf balls while they are still rolling."Michael Phelps on Mark Twain
"Golf is a good walk spoiled."Michael Phelps on Mark Twain

"This is my 20th year in the sport. I've known swimming and that's it. I don't want to swim past age 30 if I continue after this Olympics, and come back in 2016, I'll be 31. I'm looking forward to being able to see the other side of the fence."
"I have reached a place in my life where I need to sit down and say, 'Well, what do I do? What's best for me?' I need to look into options for the future."
"If you want to be the best, you have to do things that other people aren't willing to do."
"I want to test my maximum and see how much I can do. And I want to change the world of swimming."
"I want to be able to look back and say, 'I've done everything I can, and I was successful.' I don't want to look back and say I should have done this or that. I'd like to change things for the younger generation of swimmers coming along."
