Motivation

Motivation is the drive to actively work to accomplish something. It spurs one to action when one perceives that the conditions are ripe for achieving the goal. Motivation is different from mere desire; it is possible to desire something without having sufficient motivation to actively pursue that objective. Research has found that the way in which the brain handles the neurochemical dopamine plays an important role in motivation, influencing whether a person is a hard worker or a slacker. Whether a certain level of motivation is sufficient to impel one to action would presumably depend on the perceived costs, but to the extent that labor is the input required, laziness would tend to cause one to not want to make that effort.
