If Maslow were around to work on his hierarchy of needs today, he might need to make an addition to the five layers of his pyramid. The existing levels would remain the same (from bottom to top): psysiological needs, such as food and water and sex, are met first; then safety needs, followed by love/belonging needs; after those are met, we can work on our esteem needs; finally we can work on our self-actualization needs, such as morality and creativity.
