Although the book has simplicity in exploring manager role, it provides a very deep reflection on the complexity of leadership. The good parts of the book cover main areas of difficulty for new managers as well as for experienced ones diving into team development and feedback provision, looking into coaching and mentoring, supporting team motion and leading towards success. There is a good part in the book that covers own wellbeing. This area is often neglected and the results of ignoring own mental health have a strong reflection on team spirit and overall success of the team's mission. Solid advice in the book makes it a good recommendation for reading.
