"There is nothing more powerful you can do to encourage others in their quest for personal mastery than to be serious in your own quest.
Personal mastery is used for the discipline of personal growth and learning. People with high levels of personal mastery are continually expanding their ability to create the results in life they truly seek. From their quest for continual learning comes the spirit of the learning organisation.
Personal mastery goes beyond competency and skills, though it is grounded in competence and skills. It goes beyond spiritual unfolding or opening, although it requires spiritual growth. It means approaching one's life as a creative work, living life from a creative as opposed to reactive viewpoint."
Peter Senge, The Fifth Discipline, 1990
"The individual who has developed a high level of personal mastery is a self-directed, self-motivated, self-actualized but team-oriented, transcendent individual who is powered ceaselessly by his belief of self-efficacy, continuous quest for learning and knowledge and guided by a noble sense of purpose whilst understanding his role as a knowledge creator, contributor and learning catalyst in relation to his self, family, community, organisation and country."
Tuck-Wai KOH, Achieving Personal Mastery, 1997
