A mentor isn't someone who provides step-by-step instructions. The most powerful learning comes from finding someone you admire and closely observing their every move, how they speak, and how they behave in the face of obstacles, rather than seeking direct guidance.

While acknowledging the benefit of having mentors, Herb Wagner has found that the process of being a mentor is even more educational. Teaching and guiding others forces a deeper understanding of one's own principles and provides fresh perspectives from the next generation, offering greater personal and professional growth.

As a company grows, new hires lack the context of early struggles. To preserve the original culture, formally document and share stories of early failures, pivots, and near-death experiences during onboarding. This reminds everyone of the core principles that led to success.

Co-founder Slava Rubin initially dismissed defining company values as a waste of time. Co-founder Danae Ringelman championed the process, and its success was proven when Slava later asked her to return from leave specifically to reinforce the company's culture, highlighting the essential value of this work.

A professor is capturing the GSB's history not as a formal record, but as an "appreciation" told through stories. This approach treats institutional history as a living narrative to convey culture and answer "what is this place about?" It moves beyond mere facts, figures, and rankings to communicate the organization's soul.

Sequoia frames leadership changes not as takeovers but as "intergenerational transfers" of stewardship. This cultural focus on leaving the firm better than they found it is key to its longevity and successful transitions, a model for any long-term partnership.

A 52-year veteran professor argues that amid radical demographic and curricular shifts at Stanford GSB, the two constants are the physical campus and its "forward-looking vibe." This suggests an institution's sense of place and a consistent ethos can provide stability and continuity during profound transformation.

The young founder hired an experienced executive who became a mentor and effectively his boss. He learned more from observing this leader's actions—how he interacted with people and approached problems—than from direct instruction. This demonstrates the power of learning through osmosis from seasoned operators.

Culture isn't about values listed on a wall; it's the sum of daily, observable behaviors. To build a strong culture, leaders must define and enforce specific actions that embody the desired virtues, especially under stress. Abstract ideals are useless without concrete, enforced behaviors.
