Personal development or self-improvement consists of activities that develops a person's capabilities and potential, enhance quality of life, and facilitate the realization of dreams and aspirations. Personal development may take place over the course of an individual's entire lifespan and is not limited to one stage of a person's life. It is not restricted to self-help and can include official and informal actions for developing others in roles such as a teacher, guide, counselor, manager, coach, or mentor. When personal development takes place in the context of institutions, it refers to the methods, programs, tools, techniques, and assessment systems offered to support positive adult development at the individual level in organizations. More recently, it is recognised that workplaces should be more proactive in providing personal development. Bob Aubrey (Founder & Chair of the Advisory Board of the ASEAN Human Development Organisation) contends "that human development should be integral to policies and practices in the workplace".
