Success

I hated every minute of training, but I said, 'Don’t quit. Suffer now and live the rest of your life as a champion.'

Don’t count the days, make the days count.

Float like a butterfly, sting like a bee.

I think it's really important to believe in yourself, because if you don't, then who will, sweetie?

You have to believe in yourself when no one else does, that makes you a winner right there.

Luck has nothing to do with it, because I have spent many, many hours, countless hours, on the court working for my one moment in time, not knowing when it would come.

I always believe I can beat the best, achieve the best. I always see myself in the top position.

When you do something best in life, you don't really want to give that up, and for me it's tennis.

I'm just really enjoying myself in the process, and really enjoying the tournament.

For me, I'm focused on what I want to do. I know what I need to do to be a champion, so I'm working on it.

I told you all I was going to be No. 1, and I did just that.

Dreams are free. Goals have a cost. Time for a plan.

Worrying gets you nowhere. If you turn up worrying about how you're going to perform, you've already lost.

I know what I can do, so I never doubt myself.

To be successful you have to have your heart in your business, and your business in your heart.

You can’t be afraid to fail. It’s the only way you succeed.

In football as in watchmaking, talent and elegance mean nothing without rigour and precision.

I always thought I wanted to play professionally, and I always knew that to do that I'd have to make a lot of sacrifices.

You have to fight to reach your dream. You have to sacrifice and work hard for it.

I start early and I stay late, day after day, year after year. It took me 17 years and 114 days to become an overnight success.
