Leno believes his "low self-esteem" is a professional advantage. By assuming he's not the smartest person in the room, he remains open to expert advice and empowers his team, fostering a culture where anyone can voice concerns for a better final product.

Effective leadership isn't about one fixed style. It’s about accurately reading a situation and adapting your approach—whether to be directive, empathetic, or demanding. Great leaders know that leading senior executives requires a different approach than managing new graduates.

To avoid influencing their team's feedback, leaders should adopt the practice of being the last person to share their opinion. This creates a psychologically safe environment where ideas are judged on merit, not on alignment with the leader's preconceived notions, often making the best decision obvious.

To introduce a new idea, a leader shouldn't dictate terms. Instead, they should pose it as a discussion topic and listen to the language the team uses (e.g., "cost of living" vs. "inflation"). Adopting their terminology builds shared understanding and makes people feel heard, which enables collective action.

When leading functions outside your core expertise (e.g., product leading tech and data), credibility cannot come from having answers. Instead, it's built by consistently asking open-ended questions to deeply understand the team's challenges. This approach prevents solutionizing and fosters trust.

Better products are a byproduct of a better team environment. A leader's primary job is not to work on the product, but to cultivate the people and the system they work in—improving their thinking, decision-making, and collaboration.

To encourage participation from everyone, leaders should focus on the 'why' behind an idea (intention) and ask curious questions rather than judging the final output. This levels the playing field by rewarding effort and thoughtfulness over innate talent, making it safe for people to share imperfect ideas.

AT&T's CMO Kellen Smith-Kenny encourages her team to be a "thermostat" that regulates a room's energy, rather than a "thermometer" that just reflects it. This means introducing data into a creative brainstorm or bringing a customer insight into a deeply analytical discussion to achieve balance.

A top-performing CEO adapted the board practice of an "executive session." He periodically removes himself from his own leadership meetings and asks an HR leader to gather candid feedback on his performance. This powerfully models vulnerability and a commitment to continuous improvement for the entire organization.
