"Quixotism is the description of a person or an act that is caught up in the romance of noble deeds and the pursuit of unreachable goals. It also serves to describe an idealism without regard to practicality. An impulsive person or act can be regarded as Quixotic. Quixotism is usually related to "over-idealism", meaning an idealism that doesn't take the consequences into account. It is also related to naïve romanticism and to utopianism." Wickipedia
