Serena Williams gives a never before seen look into what it takes and what went into winning a few of my Grand Slams.

A lot of people reach middle age having achieved some career success and ask themselves: Well, now what? Apparently this happens even if you’re Serena Williams.

Williams, who’s now 42, retired from competitive tennis a little under two years ago.

She won 23 Grand Slam tournaments, more than any woman in the Open era and one shy of the record.

Her level of fame and achievement — both on and off the court — broke boundaries for Black women and female athletes in general. She is, by most accounts, the best ever at what she did.
