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.

You just have to prove to yourself that you can go out there and be the best that you can be and not prove anything to anyone.

Dad thanks for leaning in by helping me become a role model for young girls.

I never left my roots. You can identify me as someone that didn't become high and mighty. Humility is a defining [trait] all of us can forever learn, and I try to be as humble as anyone can be.

I don't want to end my career and then start something. I like to do something while my career is still hot and I've always enjoyed designing.

You can't underestimate anyone.

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