Battery Life: Managing Energy

Battery Life: Managing Energy

In this episode, John Nasr and Liz Kelly explore a leadership skill that rarely gets the attention it deserves: managing energy. They look at how a leader’s presence influences team dynamics in internal meetings, client interactions, and executive forums and how those signals shape how others respond. Drawing on their coaching work with senior executives, Liz and John explain how consistency in tone and behavior builds trust in high-stakes environments. They also share techniques to help leaders prepare for important moments, reset between meetings, and bring steady leadership to every interaction.
