Boredom also has its benefits. It is important to see boredom as a “call to action” (Svendsen, 1999). Nietzsche suggested that men of rare sensibility value boredom as an impetus to achievement. Boredom can be a catalyst for action. It can provide an opportunity for thought and reflection. It can also be a sign that a task is a waste of time—and thus not worth continuing.
Different scholars use different definitions of boredom, which complicates research. Boredom has been defined by Cynthia D. Fisher in terms of its main central psychological processes: "an unpleasant, transient affective state in which the individual feels a pervasive lack of interest and difficulty concentrating on the current activity." Mark Leary et al. describe boredom as "an affective experience associated with cognitive attentional processes." In positive psychology, boredom is described as a response to a moderate challenge for which the subject has more than enough skill.[full citation needed]
The bored antihero became prominent in early 20th century existentialist works such as Franz Kafka's The Metamorphosis (1915), Jean-Paul Sartre's La Nausée (1938) (French for 'Nausea'), and Albert Camus' L'Étranger (1942) (French for 'The Stranger'). The protagonist in these works is an indecisive central character who drifts through his life and is marked by ennui, angst, and alienation.
Without stimulus or focus, the individual is confronted with nothingness, the meaninglessness of existence, and experiences existential anxiety. Heidegger states this idea as follows: "Profound boredom, drifting here and there in the abysses of our existence like a muffling fog, removes all things and men and oneself along with it into a remarkable indifference. This boredom reveals being as a whole." Schopenhauer used the existence of boredom in an attempt to prove the vanity of human existence, stating, "...for if life, in the desire for which our essence and existence consists, possessed in itself a positive value and real content, there would be no such thing as boredom: mere existence would fulfil and satisfy us."
There was also a piano, well littered with music, a sewing bag thrown down upon a cretonned window seat, and the generous fireplace was flanked by two huge baskets, one heaped with magazines, the other a perfectly round mound of yellow fur, which suddenly took form and life as a yellow tabby cat fastened hopeful topaz eyes upon them, blinked away a brief disappointment, and then yawned with ennui.
