Will and motivation are two extremely important mental processes. The will is realized by referring to human activity, through which needs are satisfied, ideas are drawn and fulfilled, new aspirations are foreshadowed. This implies the realization of a relationship between desires and preset goals, which must be in accordance with the possibilities of accomplishment. Sometimes desires appear in the form of motives, which induce in our consciousness a force for the fulfillment of the purposes of actions. Contemporary psychology believes that the will will be imposed as the main way of organizing and regulating the development of all other processes and psychic phenomen. Also, it is considered that the will is closely related to the human personality, being considered by some psychologists as a personality trait. Also personality is related to motivation, the essential component of any activity, with a role in signaling physiological or psychological deficits that includes needs, motives, interests, beliefs, tendencies, intentions, desires, aspirations. It energetically supports the activities in order to satisfy their own needs, contributing to the formation and development of some personality traits. We consider that there is a close relationship between what the individual wants and why he behaves in a certain way. Both, the will and the motivation, involve action to achieve the purpose, although the will is a superior form of the desire, which is a component part of the motivation. However, the motivation awakens and stimulates the desire, but not the will, although the motivation is the one that stimulates the will.
