Maslow referred to the lower four levels as “deficiency needs” because if they are not met we become anxious or distressed. But when they are fulfilled, we do not notice and move up to the next level. This means the fundamental human needs to ensure basic happiness are the bottom four levels of the pyramid. The top level is the need for self-actualization and reaching your full potential. While this is important, the majority of people are unable to attain this level because progress up the levels is often disrupted by failures to satisfy lower needs. For example, you are less likely to be concerned with what others think of your flashy car if you just lost your job and no longer have income to feed and shelter yourself.
