Success requires a paradoxical mindset: commit to a long-term vision (e.g., a decade) while being relentlessly consistent with daily actions. Compounding only works over long time horizons, so outlast competitors by sticking to the process for the 'thousand days' it takes to see exponential growth.

The act of choosing long-term health over the instant gratification of alcohol rewires your brain to favor delayed gratification. This mental muscle is directly transferable to business, fostering the patience and financial discipline required for long-term strategic investments and planning.

Post-mortems of bad investments reveal the cause is never a calculation error but always a psychological bias or emotional trap. Sequoia catalogs ~40 of these, including failing to separate the emotional 'thrill of the chase' from the clinical, objective assessment required for sound decision-making.

While long-term focus is a virtue, investment managers at WCM warn it can become an excuse for inaction. During periods of significant market change, blindly "sticking to your knitting" is a liability. Recognizing when to sensibly adapt versus when to stay the course is a critical and nuanced skill.

Simply "thinking long-term" is not enough. A genuine long-term approach requires three aligned components: 1) a long-term perspective, 2) an investment structure (like an open-ended fund) that doesn't force short-term decisions, and 3) a clear understanding of what "long-term" means (10 years vs. 50 years).

The key lesson from Exor is that patient, long-term investing doesn't mean avoiding action. Learned from an early survival crisis, their leadership makes a few specific, intentional decisions each year to refresh the portfolio, demonstrating that decisiveness is critical even with a multi-generational time horizon.

While having a disciplined rule like reviewing a stock after 24 months is useful, it should be subordinate to a more critical rule: sell immediately if the fundamental investment thesis breaks. This flexibility prevents holding onto a losing position simply to adhere to a predefined timeline.

In a market dominated by short-term traders and passive indexers, companies crave long-duration shareholders. Firms that hold positions for 5-10 years and focus on long-term strategy gain a competitive edge through better access to management, as companies are incentivized to engage with stable partners over transient capital.
