Book excerpt: Momentum is your greatest ally – with it you can do anything, without it you will stall. As CEO you hate surprises, especially the kind that undermines momentum - yours or the organization you lead. Every CEO's journey is unique. However, there exists a very predictable, but previously unknown pattern: the CEO life cycle. The Four Dilemmas of the CEO outlines the common challenges that every CEO will face during their tenure, irrespective of geography or industry. Once understood, action can be taken to break through these glass ceilings that cause CEOs to get stuck in the business, while their mandate for working on the business is continually diverted. Framed within the life cycle of a CEO, the Four Dilemmas are: 1. You're in charge of everything, but cannot completely trust anything. 2. You know that today's executive cannot deliver tomorrow's results. 3. How do you engage the full capability of your executive on the business when their reputations were earned working in the business? 4. At what point does the price of remaining personally relevant outweigh your other options? In the first book to focus on the life cycle of a CEO, the authors draw on decades of international experience, both as former CEOs and trusted advisers, to show every executive how to recognize and anticipate the individual dilemmas, master them, and accelerate through them.
