4. Respect and recognition

Maslow divided these needs into two types: self-esteem (self-esteem, personal achievements, independence from others) and to be respected by others. A person wants to feel important both in his own eyes and in the eyes of other people. Self-esteem is directly related to a sense of self-confidence and self-worth, with self-acceptance and self-worth. Respect from others is associated with the desire to be approved by others, successful and appreciated.


5. Self-actualization

Maslow considers, that self – actualization is the ability of a person to do what he was created for. A musician feels the need to make music, an artist – to draw, a poet – to write. If a person wants to be happy, he must do what he was born for. This desire to develop one's potential is the highest need in Maslow's hierarchy. At the same time, the psychologist notes that the specific behavior into which this need will develop varies from person to person. For one, this will be expressed in the desire to become an ideal parent, for another it will be associated with sporting achievements, for a third it will be a joy to create or invent.
