Serena Williams wrote an essay for Vogue announcing her retirement from professional tennis.

Seven times Williams has won the Australian Open. She is considered to be one of the greatest tennis players of all time and is referred to as the G.O.A.T. Williams. She won her first major title at the age of 17 after defeating Hingis at the U.S. Open. Williams won four gold medals at the Olympics.

I don't like the wordretirement. It doesn't feel like a modern word to me. I want to be careful about how I use that word because it means something very specific and important to a community. I think the best way to describe what I'm up to is evolution.

Williams told readers that she was torn about continuing to play tennis.

She wrote that she hates that she has to make a decision. I want it to be easy for me, but it isn't. I'm ready for what's next but I don't want it to end.

Williams and Ohanian have a daughter. When she was pregnant, Williams won the Australian Open. Williams says in the essay that she is getting ready for baby number two and will have its own set of challenges.

In the last year, we have been trying to have another child, and recently got some information from my doctor that made me feel that we can add to our family whenever we're ready."

The athlete-turned-entrepreneur has been so excited about being a part of her daily life that her balance of interest has been slowly shifting towards her venture capital fund.

The childhood of Williams and her sister, Venus Williams, was dramatized in a movie. Will Smith won the Oscar for best performance by an actor in a leading role for his role in "Concussion."

Serena Williams isn't sure if she's ready to win the U.S. Open but she's going to try.

I don't like thinking about my past. I don't know what to say when people ask about it. Women athletes feel that they can be themselves on the court thanks to the opportunities afforded to them by me. I think I went through some hard times as a tennis player so that the next generation could have it easier.

The net worth of Serena Williams is $250 million.
