Remember Malcolm Gladwell's famous "10,000-hour rule" from his bestselling book Outliers? It proposes that achieving mastery in any field requires roughly 10,000 hours of practice, emphasizing the importance of early professionalization and intensive practice for becoming an elite in a particular field.

This approach, known as "deliberate practice", encourages setting goals from a young age, investing time and specializing in a specific field. On paper, it sounds like a good path to success, but when we look at the lives of elite athletes, musicians and scholars, we find a different story. In reality, many individuals who have risen to the top of their respective fields took a more diverse and winding route. They often explored a wide range of activities, gained a broad skill set, and only specialized at a later stage in life. In other words, the idea that one must know one's specialization from a young age is fundamentally wrong.

Studies have shown that an approach called the "sampling period" is often more effective for achieving success. During this phase, individuals try various activities, gain diverse skills, identify their strengths and weaknesses, and only choose a field to specialize in once they have a clearer understanding of their passions and abilities.

Elite athletes, for example, rarely specialize in a single sport at a very young age. Instead, they engage in a variety of sports during their formative years, which allows them to acquire broad physical skills and discover their interests and talents. These early diversification experiences provide valuable lessons that can be applied to their chosen sports.

Consider the journey of Roger Federer, one of the greatest tennis players of all time. At the age of 6, he dabbled in rugby, skiing and wrestling, only returning to tennis later. The trial period benefited him not just because he found his true passion but also because his experiences in various sports enriched his tennis game with a unique set of skills.
