Work Smart, Be Happy; The Foundation is written for Project Managers and CEOs who operate under constant pressure—and are beginning to sense that working harder is no longer the answer.In high-responsibility roles, urgency becomes normal, stress becomes invisible, and success quietly loses its satisfaction. This book explores what most leadership literature overlooks: the inner foundations that determine whether leadership is sustainable—or exhausting.Rather than offering productivity hacks or motivational tactics, Michiel A.M. Arens invites leaders to shift the place from which they work. Drawing on lived experience and deep reflection, he shows how clarity, presence, rhythm, boundaries, trust, and meaning create a different quality of leadership—one that performs without self-sacrifice.In this book, you will discover:-Why calm is biological, not a personality trait-How stress and burnout develop beneath competence-Why effortlessness is the result of alignment, not laziness-How to lead with clarity instead of urgency-Why being matters more than having for long-term fulfilmentWork Smart, Be Happy; The Foundation offers a new approach to sustainable leadership.
