So, there is this thing called "Hierarchy of Needs", which was created by a very clever psychologist who basically cut our need into groups (physiological, safety, love, esteem and self-actualization).
Physiological needs are the physical requirements for human survival. If these requirements are not met, the human body cannot function properly, which ultimately leads to death. Physiological needs are the most important, which means they should be met first. Such needs are displayed in the picture above.
With their physical needs relatively satisfied, one's safety needs take dominate behavior. In the absence of physical safety – due to war, natural disaster,family violence, childhood abuse, etc. – people may not function well in a sense extending to lack of sleep, or no appetite, to even more serious conditions such post-traumatic stress. In this day and age there are other aspects of life that need security. Such are:
- Personal security
- Financial security
- Health and well-being
According to Maslow, humans need to feel a sense of belonging and acceptance among their social groups, regardless if these groups are large or small. Humans need to love and be loved – both sexually and non-sexually – by others. If there are deficiencies in this sector, then the individual will not be able to form any meaningful relationships in the future.
All humans have a need to feel respected; this includes the need to have self-esteem and self-respect. Esteem presents the typical human desire to be accepted and valued by others. People often engage in a profession or hobby to gain recognition, like the satisfaction one gets while boasting about any and every achievement of theirs.
Self-actualization is difficult to define. A self-actualizer is a person who is living creatively and fully using his or her potentials. This is the principle that sits behind "Carpe diem" and "what a man can be, a man must be".
