Learning and growth: your skills and learning ability. How do you learn, and how can you be successful in the future? For example, the course that you are taking in conjunction with this book may lead to a degree, be a prerequisite for other courses, and so on.
Internal: your physical health and mental state. How can you control these to create value for yourself and others? How can you remain feeling good at work as well as in your spare time? For instance, your objectives and activities related to physical and emotional fitness.
Customer (external): relations with your spouse, children, friends, employer, colleagues, and others. How do they see you?
Financial: financial stability. To what degree are you able to fulfill your financial needs? Again, do you seek financial independence, resources to fund other endeavors?
Your objective should be to develop your personal vision statement and list several areas of development in learning, internal, customer, and financial facets of the scorecard. You should be able to fit the scorecard on a single page, for easy and frequent reference.
Moving forward you should reference this as a way to assess your own personal growth progress and a way to ensure you are on track.
