I’m unsure of a specific book, perhaps if you post regarding your needs, it will invite others to comment and share books that may help you in this space. If you can’t identify a book, simply capture your career goals for 2020, think about areas of opportunity as well as actions you can take that are developmental in nature/that help you achieve your goal. One of my goals, for example is to attend Bishop TD Jakes Leadership Conference next year. He’s a global leader and visionary, therefore I’m planning to not only expand my ability to lead but also my ability to think bigger; more global.
