Personal development covers activities that improve awareness and identity, develop talents and potential, build human capital and facilitate employability, enhance the quality of life and contribute to the realization of dreams and aspirations. Personal development takes place over the course of a person's entire life. Not limited to self-help, the concept involves formal and informal activities for developing others in roles such as teacher, guide, counsellor, manager, life coach or mentor. When personal development takes place in the context of institutions, it refers to the methods, programs, tools, techniques, and assessment systems that support human development at the individual level in organizations.
