#12: Serena Williams

Habit: Certain pre-game rituals

With 23 Grand Slam singles titles to her name, Serena Williams embraces a “if it ain’t broke, don’t fix it” approach regarding her game-day rituals. In 2012, The London Standard highlighted a few of her quirks: she ties her shoelaces the same way and bounces the ball five times before her first serve and twice before the second.

“I have too many superstitious rituals, and it’s annoying,” she admitted. For Serena, these routines have become as much a part of her performance as her powerful serve, reflecting the intense focus and precision behind her legendary career.
