This is about how legendary rugby coach Jack Clark builds high-performance teams. His core idea: values must be your daily decision-making system, not just posters on the wall. He emphasizes a mindset: 'Grateful for everything, entitled to nothing' — when you don't feel owed anything, you focus on the next most important thing. No stocks or funds are mentioned, but if you lead a team or want to improve yourself, his 'meritocracy' (rewarding current performance, not tenure) and 'leave leadership in the middle' (anyone can lead) are worth noting.
In this episode of Invest Like the Best, the report features an interview with Jack Clark, head coach of the University of California rugby team, exploring how to build high-performing teams. Since taking the helm in 1984, Clark has achieved a remarkable 90% win rate, setting records with a 98-game
University of California rugby head coach Jack Clark (career winning percentage of 90%, including two winning streaks of over 90 games) shares his philosophy for building high-performance teams. Core judgment: Team values must become the daily operating system, not slogans on the wall — "If you ask 10 employees what the company's values are and they hesitate to answer, then those values are meaningless."
Clark observes that in most organizations (sports teams and corporations alike), values are merely "wall slogans"—they look good in presentations and annual reports, but employees cannot even remember them. He thus established a decision system with values as the filter: all personnel transactions, organizational transactions, and business transactions must be examined through the lens of values to ensure "values-based decisions" are made.
Core Five Values: Selflessness (team first, self second), Meritocracy (current performance as currency), Continuous Improvement (either get better or get worse, no middle ground), Mental Toughness (focus on the next most important thing), and Leadership (make those around you better and more efficient).
Clark emphasizes that values must be complementary and non-contradictory—"If you truly believe this, how can you also believe that?" At the same time, they require "fence-post" repetition (borrowing a football term, meaning constant reinforcement), "People will gather where there is love, so you must use these values every day, every week, not just mention them once in a quarterly meeting."
Clark proposes a core mindset framework: "Grateful for everything, entitled to nothing." This phrase has permeated many offices in Silicon Valley and New York. He argues that when a person truly believes in this statement, they become more resilient — "You don't feel like you're owed anything; you're busy getting things done."
The definition of mental toughness comes from a cricketer's expression: "The ability to focus on the next most important thing." Clark believes this is far more critical than any physical toughness — "You don't need to call on mental toughness when things are going well. When something bad happens, having the discipline to ask yourself 'What is the next most important thing?' and fully committing to it — that is true mental toughness."
Case study: Mark Bingham — a player Clark coached, one of the passengers who rushed the cockpit on United Airlines Flight 93, likely saving the U.S. Capitol building. "When the news came that the plane was heading toward a building, he didn't slump in his seat. He stood up, organized others, and tried to regain control. That is focusing on the next most important thing."
Clark argues that the core characteristic of high-performing teams is that "the currency circulating within the team is current performance" — not last year's results, not potential, not seniority. "Potential is a good thing, but you can't live off it for long. Seniority is also a good thing, but experience must translate into current performance."
Tactical Execution: Measure everything, publish results internally, celebrate successes, and recognize performance. Clark cites John Wooden's philosophy that "performance precedes results" — "Results follow performance, not the other way around. Put all your energy into performance, and the results will naturally follow."
Key Insight: Teams are either getting better or getting worse — there is no middle ground. "Sometimes we think we can coast on a plateau because we've done well before. But the truth in sports and business is that there is no middle ground."
Clark’s definition of leadership stands in stark contrast to the mainstream. He believes the traditional view (a few leading the many) “sounds like the team I want to play against.” He distinguishes between the chain of command (which must be preserved) and leadership (which should be shared):
“Keep authority intact, let the boss remain the boss, but don’t take leadership away with it. Keep leadership in the middle, accessible to everyone.”
Definition: “The ability to make those around you better and more effective” — unrelated to position, seniority, or star status. Everyone has a responsibility to contribute to the team, and the best leaders possess a “vast toolbox,” able to pull out the right tool for each situation.
The core trait Clark seeks in recruitment is non-cognitive grit — "Who will really grit their teeth and persevere? Who almost smiles when difficulties arise? Who will step into that dark closet and keep grinding when times are tough?"
Three pillars of judgment: non-cognitive grit, a love for the sport, and the ability to care about what matters (people, things, organizations). Clark quotes Bo Schembechler (University of Michigan football coach): "If you don't get the players you want, they only beat you once a year; but if you recruit the wrong people, they beat you every day."
Shift in individual development focus: In the first half of his coaching career, 80% of his energy went to the team and 20% to individuals; in the second half, it was split evenly. "We often forget that, beyond building a team, we should also help each individual get from where they are to where they want to go. Spend more time discussing individual strengths and building a blueprint for success based on those strengths."
Clark points out that the concept of teamwork is hardly taught on campus — "I work at one of the top public research universities in the world, but the concept of teamwork is not taught anywhere on campus." He believes this gives athletes a unique competitive advantage when entering the workforce: "My players have 10 years, 10,000 hours of team experience. They know what a good teammate looks like, what a bad teammate looks like, and why teams succeed or fail."
Observations on corporate culture: Culture is difficult to scale — "Most companies start small, everyone knows every new hire, everyone knows what we believe. But over time, you don’t even know who’s been hired. Culture needs to be audited regularly, just like financial audits."
Prerequisites for changing culture: It must be driven from the top — "It’s never the people in the middle who come up with an idea and push it upward. It has to be someone with the greatest authority who believes this is the right thing to do."
This section is not applicable (this issue focuses on team building and leadership topics, with no investable positions involved).
1. Clark: "Grateful for everything, owed nothing" — When you truly believe this, you become more resilient because you no longer feel entitled to anything, but instead focus on achieving your goals. This phrase has permeated many offices in Silicon Valley and New York.
2. Clark defines mental toughness: "The ability to focus on the next most important thing" — It is not about physical toughness, but the discipline to ask yourself after something bad happens, "What is the next most important thing?" and fully commit to it. You do not need to call on mental toughness in good times.
3. Clark distinguishes chain of command from leadership — "Keep authority intact, let the boss remain the boss, but do not take leadership away. Keep leadership in the middle so everyone can access it." Leadership is defined as "the ability to make those around you better and more effective."
4. Clark cites Bo Schembechler's recruiting rule — "If you don't get the players you want, they only beat you once a year; but if you get the wrong players, they beat you every day." Clark wrote this on his arm and has never forgotten it.
5. Clark's "fence post" principle — Values must be repeatedly emphasized, not a one-time declaration. "People gather where there is love, so you must use these values every day, every week, not just mention them once at quarterly meetings."
6. Clark on the shifting weight of individual development — In the first half of his coaching career, 80% of his energy went to the team and 20% to individuals; in the second half, it was split 50-50. "We often forget that besides building the team, we should also help each individual get from where they are to where they want to go."
7. Clark on teamwork as an untaught core skill — "I work at a top-tier public research university, but the concept of teamwork is not taught anywhere on campus." The unique competitive advantage of athletes is 10 years, 10,000 hours of team experience.
8. Clark on the combination of "care + demand" — Quoting Pat Summitt: "People don't care what you say until they know you care about them." The real secret is: when people know you genuinely care about them, you are qualified to keep raising the bar.
