Serena Williams went from training with her dad on the public courts in Compton to winning the US Open—six times so far. She's competing there again now, and in a new ad, Nike celebrates that incredible journey, Ad Age reports. The video combines shots of an adult Williams playing tennis with archival footage of a 9-year-old Williams and her dad on those Compton courts, complete with her dad saying in voiceover, "Be tough, just like you want to win. Just like you're at the US Open." PopSugar declares that the minute-long video "might as well be an extremely emotional short film," while Revelist calls it "goosebump-inducing." CNBC points to the "success hack" the ad illustrates: visualization. "If you can see it, you can be it." (More Serena Williams stories.)
