Goals have strong motivational effects. They provide an individual with a sense of direction and purpose. They also help to build an individual's self-efficacy. Successfully completing a goal increases an individual's self-beliefs in their capabilities. Bandura links this effect with the increase interest in what an individual is doing and the increase in self-satisfaction. Motivation through goals provide an ongoing source of self-efficacy, interest, and satisfaction. Those without these characteristics are often unmotivated and uncertain about their abilities.
