Maslow's hierarchy of needs Physiological needs are the physical requirements for human survival. If these requirements are not met, the human body cannot function properly and will ultimately fail.

Need for achievement This personality trait is characterized by an enduring and consistent concern with setting and meeting high standards of achievement. This need is influenced by internal drive for action (intrinsic motivation), and the pressure exerted by the expectations of others (extrinsic motivation). Measured with the thematic apperception test (TAT), need for achievement motivates an individual to succeed in competition, and to excel in activities important to him or her.[3]
