Grow Up is a call to Responsible leadership at all levels.
The ideals of leadership have taking responsibility as one of them. The world is now dominated by people and leaders who fail consistently at the huddle of taking responsibility. Responsible leadership will take the blame first when things go wrong, it will show its sense of duty when challenges crop up, and it will not sit idly by and do nothing in the face of identified problems.
Responsible leadership will also strive to provide solutions and not create more problems.
These essentials of Responsibility in leadership are what this book discusses.
