"I love my body, and I would never change anything about it. I'm not asking you to like my body. I'm just asking you to let me be me. Because I'm going to influence a girl who does look like me, and I want her to feel good about herself."

"I really think a champion is defined not by their wins but by how they can recover when they fall. I have fallen several times. Each time I just get up and dust myself off and I pray, and I'm able to do better or I'm able to get back to the level that I want to be on."

"I try to be the best that I can be every day. I have bad days. I had a bad day the other day. I hit for only, like, 30 minutes, and I stormed off the court. But that was the best I could do on that day. So am I the greatest? I don't know. I'm the greatest that I can be."

"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 don't pray to win. Not that I don't want to or try to. But I know now a loss can be a gift. A chance to grow. Losing has taught me to be a better winner and a better person, one who is always looking for opportunities to learn."

"We have to be thankful, and we also have to be positive about it so the next black person can be No. 1 on that list. Maybe it was not meant to be me. Maybe it's meant to be the next person to be amazing, and I'm just opening the door. Zina Garrison, Althea Gibson, Arthur Ashe and Venus opened so many doors for me. I'm just opening the next door for the next person.'"

"Growing up I wasn't the richest, but I had a rich family in spirit. Standing here with 19 championships is something I never thought would happen. I went on a court just with a ball and a racquet and with a hope."

"I have said it once and I'll say it again, this world has come so far but yet we have so much further to go. Yes, we have broken down so many barriers — however there are a plethora more to go. This or anything else will not stop me from pouring love, light and positivity into everything that I do. I will continue to take a lead and stand up for what's right." – on Instagram in 2017

"You can't fail if you do something and it doesn't work out. That's success. Maybe it wasn't to the point of success where you wanted to do it, but it's still success. There were a lot of times where I wasn't as successful as I wanted to be, but that doesn't define me. It just defines how you can come back and not let anything hold you down." – to PEOPLE in 2016
