Underperforming VC firms persist because the 7-10+ year feedback loop for returns allows them to raise multiple funds before performance is clear. Additionally, most LPs struggle to distinguish between a manager's true investment skill and market-driven luck.

Successful concentration isn't just about doubling down on winners. It's equally about avoiding the dispersion of capital and attention. This means resisting the industry bias to automatically do a pro-rata investment in a company just because another VC offered a higher valuation.

Unlike a founder focused on one company, a VC operates at the nexus of disparate stakeholder contexts (LPs, portfolio crises, new pitches). This creates a unique 'whiplash' that requires deliberate systems for prioritization and mental management to be effective.

A common mistake in venture capital is investing too early based on founder pedigree or gut feel, which is akin to 'shooting in the dark'. A more disciplined private equity approach waits for companies to establish repeatable, business-driven key performance metrics before committing capital, reducing portfolio variance.

Resist the common trend of chasing popular deals. Instead, invest years in deeply understanding a specific, narrow sector. This specialized expertise allows you to make smarter investment decisions, add unique value to companies, and potentially secure better deal pricing when opportunities eventually arise.

The hardest transition from entrepreneur to investor is curbing the instinct to solve problems and imagine "what could be." The best venture deals aren't about fixing a company but finding teams already on a trajectory to succeed, then helping change the slope of that success line on the margin.

Lior Susan highlights the biggest mental hurdle for former operators becoming VCs: internalizing the power law. Operators are builders wired to fix problems and believe they can turn any situation around. In VC, success is driven by a few massive outliers, requiring focus on winners, not on fixing every company.

The institutionalization of venture capital as a career path changes investor incentives. At large funds, individuals may be motivated to join hyped deals with well-known founders to advance their careers, rather than taking on the personal risk of backing a contrarian idea with higher return potential.

The majority of venture capital funds fail to return capital, with a 60% loss-making base rate. This highlights that VC is a power-law-driven asset class. The key to success is not picking consistently good funds, but ensuring access to the tiny fraction of funds that generate extraordinary, outlier returns.
