Abraham Maslow projected a general overview of human motivation. His theory strikes a distinctive sense of balance between biological and social needs that integrates many motivational concepts. According to Maslow individual needs are set in a hierarchy, and everyone must satisfy their basic needs before they can satisfy their higher needs. The hierarchy is portrayed as a pyramid beginning with physiological needs at the bottom and self-actualization at the top.
The 'Hierarchy of Needs' theory has four different levels before one can come to full self-actualizing. Beginning with the most basic, the needs are physiological, safety, love and belonging, esteem and lastly, self-actualization.
Physiological needs refer to the literal requirements for human survival, such as breathing, food, water, sleep, and metabolic activities. Safety needs are all things providing humans with a sense of security, such as protection from the elements, financial stability and personal health. Furthermore, love and belonging refers to the interpersonal relationship, in which relationships with family, friends, lovers, and others are drawn; providing humans with a sense of acceptance and attachments. Esteem refers to the need to be respected and accepted and, most importantly, the need of self-respect. People develop their esteem as they are recognized by others, gaining a certain level of social status and thus build their own self-respect. The last is about the self-actualization, in which an individual realizes his or her potentials.

But as Maslow’s hierarchy continues, each need is separated into very distinct and self supporting categories that – according to him – we ourselves must fill; when truth is that
