Creating leadership impact isn’t about one defining moment—it’s about the ripple effects your leadership generates over time. In this episode of Leadership Lounge, Emma Combe sits down with Shannon Knott and Erin Marie Collins to unpack what meaningful impact looks like today, and how leaders can sustain it.

They explore:

• Why impact extends beyond results to the experience others have of your leadership.
• The key skills—curiosity, adaptability, and an understanding of your purpose—that enable long-term influence.
• How to evaluate whether your leadership is truly landing across stakeholder groups.
• Why reflection and feedback loops are essential to maintaining credibility and trust.

“Leaders who can sustain real impact do so because they’re able to stay curious. They continually learn and adjust. They treat leadership less like a position and more as a practice.”

— Shannon Knott, Leadership Advisor, Russell Reynolds Associates

Roughly 1.2 billion young people will reach working age in developing countries over the next 10-15 years. However, current projections show that only 420 million jobs are expected to be created by that time, meaning millions of young people will be left without a clear path to employment.

World Bank President Ajay Banga joins Clarke Murphy and Marla Oates on Redefiners to talk about what the Bank is doing about it, and why job creation is so critical to both developing countries and the global economy. Ajay talks about what he’s doing to transform the 80-year old institution into a faster, more efficient, and more impactful partner in development, including partnering more with the private sector to increase investments in emerging markets. He also discusses what he calls the Decency Quotient and how leaders can tap into that in order to lead people with a hand on their back, not in their face.

We’ll also hear from Rebecca Hart, a leadership advisor in our Atlanta office, who will discuss why the most successful leaders prioritize curiosity over having all the answers.

Four things you’ll learn from this episode:

1. How to get everyone aligned with a bold mandate, mission and vision and how to deal with challenging feedback
2. Why job creation is a critical piece in global development
3. Why the private sector is critical to international development
4. What the Decency Quotient is and why it matters for leaders today
