Promoting top individual contributors into management often backfires. Their competitive nature, which drove individual success, makes it hard to share tips, empathize with struggling team members, or handle interpersonal issues, turning a perceived win-win into a lose-lose situation.

When diagnosing a failing department, stop looking for tactical issues. The problem is always the leader, full stop. A great leader can turn a mediocre team into a great one, but a mediocre leader will inevitably turn a great team mediocre. Don't waste time; solve the leadership problem first.

For teams that operate in rapid cycles, like a newsroom, the leader's most valuable trait is predictability. This consistency provides a stable foundation, empowering the team to act quickly and autonomously without being destabilized by their manager's shifting priorities, which would slow down operations.

A leader focused solely on personal wins creates a toxic environment that ultimately leads to their own apathy and burnout. They become disconnected from the very machine they built, creating a job they personally loathe despite their apparent success.

A key source of executive team dysfunction is the "empire builder"—a leader who is skilled at managing up but is ineffective in their role and hard on their team. A strong CEO identifies and removes these individuals quickly to maintain a high-performance culture.

A great salesperson transitioning to a leader often fails due to a 'selfish switch.' They hypocritically hold their team to the same work ethic standard as themselves, despite the team having significantly less financial upside. Effective leadership requires empathy for this fundamental motivational difference.

Companies often fail by promoting high-performing individual contributors into leadership without teaching them how to scale their judgment. The new leader's job is not to solve problems directly but to define what "good" looks like and enable their teams to get there.

Leaders often tolerate a top salesperson who is toxic because they drive short-term revenue. This is a fatal mistake. Tolerating this "cultural cancer" for immediate economic gain will destroy morale, increase turnover, and ultimately undermine the business's long-term health.

Newly promoted leaders often revert to their individual contributor habits of writing briefs and solving escalations. True leadership is about leverage: building a system, team, and operating rhythms that produce great decisions without the leader's direct involvement, thus avoiding becoming a bottleneck.
