I say accessorize, accessorize, accessorize. If you don't accessorize, someone else will.

We're all conditioned that we shouldn't like our brothers and sisters, that we should be angry and fight. But that's abnormal. A lot of people think that the way Serena and I are with one another is weird. It's not.

Whatever it is, people have issues and that affects you deeply. So you have to get to the bottom of it and not let that affect your life decisions and really understand why you're making the decisions you make so that way you can understand how to not do that, so I always encourage people to ask why and then to really understand you, because that's the only way to be your most successful and your most happy.

Tennis is a huge part of my life, but I don't base my self-value or my self-worth or the quality of my life on my results on the court.

Serena and I, we don't have anything to prove ... we still set a very high standard.

Sometimes, when there's a video montage. I'm thinking, 'That's my life. Oh, my God, I did that.' Yeah, it's amazing.

People ask me where I get my fighting qualities from, and I have to say Serena.
