Jack Clark has been coaching rugby at the University of California, Berkeley, longer than most of the coaches he competes against have been alive.
After 40 years at the same school, producing 24 National Championships and 135 All-Americans, he has learned a thing or two about what motivates people.
Clark believes that one thing motivates high performers more than anything else—a leader who invests in making people better.
Above all else, top talent wants to advance their skills and improve, to learn what it takes to reach the next level of mastery. A leader who understands that and will do anything and everything to help them make significant strides soon becomes a teacher, mentor, friend, and confidant.
From that position, Jack Clark inspires his players to learn and to work hard together to develop their skills and talents.
In Clark’s view, there is no better feeling in the world than knowing you are making progress and getting better. He purposely tries to create that feeling in his players and within his teams.
He asks his players to chase improvement every day and every practice, constantly pointing out when they are acquiring new skills and developing new strengths.
In private meetings, he focuses on a player’s strengths and “blows them up,” embroidering them with specifics, making them seem even bigger than they are. Then he challenges them to push harder, to make their strengths even stronger, and to capitalize on what they do best.
Every time he points out that a player has made marked improvement, he earns their implicit permission to demand even more.
Clark believes the confidence and momentum players experience from his amplification of their strengths equip them to accept the critical feedback, high expectations, and difficult practices that improvement requires.
Blowing up their strengths gives his players an armor of thick skin to ward off feelings of inadequacy or self-doubt. It is this balance of magnified strengths and intense feedback that propels them forward, allowing continuous progress and improvement.
Jack Clark’s approach offers a powerful lesson for leaders in every field. The most effective path to high performance runs through growth, not just achievement.
By making improvement visible, celebrating strengths with specificity, and creating a team culture where progress is expected, Clark has built something far more durable than a winning record. He has helped shape players who chase excellence not because they are told to, but because they have experienced the incomparable feeling of knowing they are getting better.
