I don't like to lose-at anything... Yet I've grown most not from victories, but setbacks. If winning is God's reward, then losing is how he teaches us.

I've been writing, but I haven't been writing. In my mind I've been saying I want to write, but I haven't actually physically picked up a pencil and started writing.

I need to be at my peak and my best is holding up the trophy. Anything less I wouldn't be really excited about. So that's all I can focus on.

I played pretty well in my twenties, don't get me wrong! But my consistency is better [in my thirties], my momentum is better, my wins are quicker.

I never thought about leaving a tennis legacy. I always thought about leaving a legacy of fulfillment, living out your dreams, and giving back.

I'm thankful to my family, friends, and fans for all of their support.

We all know who the real number one is. Quite frankly, I'm the best in the world.
