Maslows hierachy of needs is often potrayed in the shape of a pyramid. With the largest and lowest needs at the bottom and the need for self acyualization at the top (every day life events). The four lower layers of the pyramid are call deficiency needs physiological, security of position, friendship and love, and esteem. With the exception of the lowest (physiological) needs, if these "deficiency needs" are not met, the body gives no physical indication but the individual feels anxious and tense. Physiological needs are essential to life every animal including humans can not survive without these things. Safety are things u do in order to stay alive, you do not need these things to stay alive but it helps. Love/belonging are events in your life you want to have. Esteem are things you want to achieve like the respect by others and confidence and achievement. Self actualization is the level of need pertains to what a person's full potential is and realizing that potential. Maslow describes this desire as the desire to become more and more what one is, to become everything that one is capable of becoming.
