While this is definitely a very specific (business/corporate) approach to leadership, I still think the path it lays out is useful for you to review and make your own. Especially if you do not have a strong mentor or have gone through useful management trainings, having this to guide you through things like creating a shared vision, collecting feedback, creating an inclusive culture that celebrates wins and losses--this book scratches the surface at a few different ways to do that. Working at a nonprofit, I would not directly apply some of these approaches with my own team, but again, the framework (and the accompanying workbook) is helpful to actually think through and work out how you can apply these to your team and your current role, as well as the type of leader you envision yourself to be.
