1. Motivation is driven by an individual's needs and goals. Needs are innate physiological needs or acquired psychological needs, while goals are the results that individuals seek to fulfill their needs.
2. Maslow's hierarchy of needs proposes that people seek to fulfill lower-level physiological and safety needs before pursuing higher-level social, ego, and self-actualization needs.
3. Motivation is dynamic as needs and goals change based on life experiences, with new needs emerging and goals adapted as other needs are satisfied or not attained.
