I'm playing to around 30% of my potential - you'd be shocked at what I could do.

It's remarkable she [Venus Williams] plays at all, given her Sjögren's syndrome [an autoimmune disorder that can cause joint pain]. She's back, winning tournaments. She didn't allow society to tell her, "You have this disease; you can't do that anymore." I look at her, like, "She's not playing at 100 percent. You are. You don't have excuses." Knowing what she went through helped me try to be a more positive person.

Sure, I've been on the Tube...I caught it to Eastbourne once.

I love going shopping.

Venus [Williams] has an amazing line; I love her collection. I'm always at her office. She has an interior design company and her EleVen company. They have a wonderful office space and I'm always there for the interior part and get to see what she's doing with EleVen.

I love tennis more than designing because it's actually easier and I don't get nearly as nervous.

To this day, I don't love my arms. People want more fit arms, but my arms are too fit. But I'm not complaining. They pay my bills.
