Managers are failing everywhere, and there’s no one to help them. This is a major problem, but there's no need to worry, as I have provided the necessary solutions in this book. To become a great manager requires diligent effort and continuous practice. Even after you learn, practice, refine your skills, and gain some experience, you will still make mistakes. The good news is that you can become a better manager, regardless of your personality. It doesn't matter if you are extremely introverted or naturally extroverted. People with these two personalities – and all others in between – simply need to focus on work, and more importantly, the right kind of work. To become a great manager, you only need to learn, develop, and practice a few behaviors. Unfortunately, the world has conspired to confuse the average manager by offering a mix of bad advice, good but hard-to-apply advice, excessive or confusing or conflicting advice, or no advice at all. Often, those who promoted you leave you without guidance. As for those who write books on management, their theoretical knowledge sometimes outweighs their practical experience.
