Aspiration can be positive since it allows motivation. For example, the aspiration of one day owning a car motivates a person to work hard. On the other hand, this can have a negative effect when the aspirations are are set too high and not met for instance, someone aspiring a goal of becoming a millionaire was not met. This could affect the person by causing them to loose all motivation and potentially loose themselves and other aspirations.
