We define Personal Mastery as growing as a person and as a professional. Mastery is in the growth process, not in reaching some 'end state'. You can always continue to improve yourself.
This growth is one continuous learning process that can be fed in two ways. Formal, through education, training, workshops, etc. And informal, through experiences from (daily) practice and through, for example, discussions with colleagues, customers and managers.
The biggest challenge lies in this informal learning. The moment you become a 'master' in this, then working and learning become one. This makes you more effective in what you do and how you do it. You have, as it were, developed a Lifelong Learning methodology for yourself without having to invest too much extra time.
This e-learning module will help you get started with this Personal Mastery process.
