The basis of Maslow's theory of motivation is that human beings are motivated by unsatisfied needs, and that certain lower needs need to be satisfied before higher needs can be addressed. Per the teachings of Abraham Maslow, there are general needs such as physiological, safety, love, and esteem(Food, clothing, shelter are most essential), which have to be fulfilled before a person is able to act unselfishly. These needs have been dubbed "deficiency needs."
    The Maslow chart is intended to be read from the bottom up.

    A person cannot move to a higher level until each preceding level is satisfied.

    When the conditions around you change, your needs probably change too.
