If you’ve read the book The Tipping Point: How Little Things Can Make a Big Difference by Malcolm Gladwell, you know the story of Wayne Gretzky, and how he became the greatest hockey player of all time. Every day after school, Wayne practised hockey on the rink that his father had created in their backyard. The book also talks about renowned musician Yo-Yo Ma, who spent hours practising his cello. What do these two have in common? They spent countless hours honing their craft, which is the catalyst to the 10,000 hours needed to become an expert at anything.
