Serena Williams's children's guide is kind of here. The tennis legend spoke out about "The Adventures of Qai Qai" in a September 14 interview on Good Morning America.

It was based largely on the doll of the same name that her daughter Olympia used to make her children's guide.

Williams stated that she is almost using her creativity to create the guide because children have so much creativity.

She stated that she simply wanted to "just put in people's minds that we won't forget how important it's just to use your creativity and play and in addition imagine for yourself."

"So, there are some really cool hidden messages there about self-confidence. You can do it. In addition to simply being a child again.
