Motivation refers to factors that cause us to act in specific ways. There are seven rules of motivation including setting goals, finishing projects, socializing with similar people, learning how to learn, matching interests and talents, increasing knowledge in inspiring subjects, and taking risks. Motivation theories include instinct theory, drive reduction theory, incentive theory, and cognitive theory. Biological needs are requirements for survival while social needs are learned through experience, such as achievement, affiliation, autonomy, and self-actualization. Maslow's hierarchy of needs proposes satisfying basic physiological needs before advancing to higher social needs.
