Despite years of effort to understand effective leadership, the challenges remain difficult and elusive. Most CEOs don't last five years in the job due to the unforgiving demands for high-level performance, leading to feelings of loneliness, weight of responsibility, and relentless criticism. The pressure to build strong teams, maintain a constant schedule, and make tough decisions can be overwhelming. These challenges, common to all leaders, are explored in "The CEO Test" by authors Adam Bryant and Kevin Sharer, drawing on wisdom from hundreds of executives. Bryant has interviewed over 600 CEOs, while Sharer has extensive experience as a CEO. In a rapidly changing business environment, mastering foundational leadership skills is crucial for success, making "The CEO Test" essential reading for aspiring leaders.
