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."[27] 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."[28]
Although it has not been widely studied, research on boredom suggests that boredom is a major factor impacting diverse areas of a person's life. People ranked low on a boredom-proneness scale were found to have better performance in a wide variety of aspects of their lives, including career, education, and autonomy.[30] Boredom can be a symptom of clinical depression. Boredom can be a form of learned helplessness, a phenomenon closely related to depression. Some philosophies of parenting propose that if children are raised in an environment devoid of stimuli, and are not allowed or encouraged to interact with their environment, they will fail to develop the mental capacities to do so.
Lethargy is a state of tiredness, weariness, fatigue, or lack of energy. It can be accompanied by depression, decreased motivation, or apathy. Lethargy can be a normal response to boredom, inadequate sleep, overexertion, overworking, stress, lack of exercise, or a symptom of a disorder. When part of a normal response, lethargy often resolves with rest, adequate sleep, decreased stress, and good nutrition.[21][22]
The expression to be a bore had been used in print in the sense of "to be tiresome or dull" since 1768 at the latest.[4] The expression "boredom" means "state of being bored," 1852, from bore (v.1) + -dom. It also has been employed in a sense "bores as a class" (1883) and "practice of being a bore" (1864, a sense properly belonging to boreism, 1833).[5] The word "bore" as a noun meaning a "thing which causes ennui or annoyance" is attested to since 1778; "of persons by 1812". The noun "bore" comes from the verb "bore", which had the meaning "[to] be tiresome or dull" first attested [in] 1768, a vogue word c. 1780–81 according to Grose (1785); possibly a figurative extension of "to move forward slowly and persistently, as a [hole-] boring tool does."[6]
“Boredom is a flight from what is important. Like workaholism and perfectionism, it is a way of distracting yourself from inner experiences. It occurs when you look outward and do not find anything to engage your attention. Instead of feeling your emotions - becoming aware of the functioning of your energy system - you become bored. Boredom ... is a flight from your higher potential. It is fear of the transformation that wants to occur, and will occur in you, when you explore your emotions. It is your resistance to spiritual growth.”
Some individuals are more likely to be bored than others. People with a strong need for novelty, excitement, and variety are at risk of boredom. These sensation seekers (e.g., skydivers) are likely to find that the world moves too slowly. The need for external stimulation may explain why extroverts tend to be particularly prone to boredom. Novelty seeking and risk-taking is the way that these people self-medicate to cure their boredom. 
These authors suggest that attention plays an important role in creating boredom. In particular, there are a few conditions that need to be met for people to feel bored. First, people need to have a reasonable level of psychological energy or arousal to feel bored. When people have low arousal and there is not much happening in the world, then they often feel relaxed. When they have high arousal, though, they have energy they would like to devote to something, but they cannot find anything engaging.

The highest levels of arousal and negative emotions. A person in a reactant boredom state has a strong motivation to escape his or her boring situation and avoid those responsible for it (such as teachers or a boss). Reflects significant restlessness and aggression. There are persistent thoughts about specific, “more highly valued alternative situations.”

Martin Heidegger wrote about boredom in two texts available in English, in the 1929/30 semester lecture course The Fundamental Concepts of Metaphysics, and again in the essay What is Metaphysics? published in the same year. In the lecture, Heidegger included about 100 pages on boredom, probably the most extensive philosophical treatment ever of the subject. He focused on waiting at railway stations in particular as a major context of boredom.[25] Søren Kierkegaard remarks in Either/Or that "patience cannot be depicted" visually, since there is a sense that any immediate moment of life may be fundamentally tedious.
Without stimulus or focus, the individual is confronted with nothingness, the meaninglessness of existence, and experiences existential anxiety.

Boredom is caused by lack of interest. You can have many hobbies or none at all, you can be around a group of people, or all by yourself. Boredom is not caused by the environment, nor the activities. It is a matter of the heart. If you have many interests you will never be bored but then again you can have only one interest, and still never be bored. If you follow your heart and act upon your hearts desires, there are numbers of possible emotions and mental states, however, boredom would not be one of them. Boredom is a state of mind that is close to blank, or a heart that is empty with no ...
Absent-mindedness is where a person shows inattentive or forgetful behaviour.[20] Absent-mindedness is a mental condition in which the subject experiences low levels of attention and frequent distraction. Absent-mindedness is not a diagnosed condition but rather a symptom of boredom and sleepiness which people experience in their daily lives. When suffering from absent-mindedness, people tend to show signs of memory lapse and weak recollection of recently occurring events. This can usually be a result of a variety of other conditions often diagnosed by clinicians such as attention deficit hyperactivity disorder and depression. In addition to absent-mindedness leading to an array of consequences affecting daily life, it can have as more severe, long-term problems.
Boreout is a management theory that posits that lack of work, boredom, and consequent lack of satisfaction are a common malaise affecting individuals working in modern organizations, especially in office-based white collar jobs. This theory was first expounded in 2007 in Diagnose Boreout, a book by Peter Werder and Philippe Rothlin, two Swiss business consultants. They claim the absence of meaningful tasks, rather than the presence of stress, is many workers' chief problem.
Then, after a baseline EEG test measuring normal brain activity, the researchers assigned the participants a tedious task: they had to turn eight virtual pegs on a screen as the computer highlighted them. This activity lasted approximately 10 minutes, during which time the researchers used EEG caps to measure participants’ brain activity as they carried out the boring task.
Grunge lit is an Australian literary genre of fictional or semi-autobiographical writing in the early 1990s about young adults living in an "inner cit[y]" "...world of disintegrating futures where the only relief from...boredom was through a nihilistic pursuit of sex, violence, drugs and alcohol".[47] Often the central characters are disfranchised, lacking drive and determination beyond the desire to satisfy their basic needs. It was typically written by "new, young authors"[47] who examined "gritty, dirty, real existences"[47] of everyday characters. It has been described as both a sub-set of dirty realism and an offshoot of Generation X literature.[48] Stuart Glover states that the term "grunge lit" takes the term "grunge" from the "late 80s and early 90s—...Seattle [grunge] bands".[49] Glover states that the term "grunge lit" was mainly a marketing term used by publishing companies; he states that most of the authors who have been categorized as "grunge lit" writers reject the label.[49]
Finally, a real problem caused by boredom is that it leads you to dislike the things that are the object of boredom. In my senior year of high school, for example, I was forced to read Moby Dick. I struggled to get interested in it and spent long hours staring at the pages trying to lose myself in it. To this day, I really do not like Moby Dick. The negative feelings that came with the boredom have stuck to the book.

Flow is a state of total immersion in a task that is challenging yet closely matched to one’s abilities, akin to “being in the zone.” Flow occurs when a person’s skills match the level of challenge presented by the environment and when a task includes clear goals and immediate feedback. Tasks that are too easy are boring. In contrast, tasks that people perceive to be too difficult lead to anxiety.
