Procrastination in the context of "Time management"

The Italian polymath Leonardo da Vinci (1452–1519) was one of the founding figures of the High Renaissance, and exhibited enormous influence on subsequent artists. Only around eight major works—The Adoration of the Magi, Saint Jerome in the Wilderness, the Louvre Virgin of the Rocks, The Last Supper, the ceiling of the Sala delle Asse, The Virgin and Child with Saint Anne and Saint John the Baptist, The Virgin and Child with Saint Anne, and the Mona Lisa—are universally attributed to him, and have aroused little or no controversy in the past. Ten additional works are now widely attributed to his oeuvre, though most have previously incited considerable controversy or doubt: the Annunciation, Madonna of the Carnation, The Baptism of Christ (with his teacher, Verrocchio), Ginevra de' Benci, the Benois Madonna, the Portrait of a Musician (with possible studio assistance), the Lady with an Ermine, La Belle Ferronnière, the London Virgin of the Rocks (with studio assistance), the Portrait of Isabella d'Este, and Saint John the Baptist.

Other attributions are more complicated. La Scapigliata appears to be attributed by most scholars, but some prominent specialists are silent on the issue. Salvator Mundi's attribution remains extremely controversial, and the extensive nature of the restoration may never allow a definitive resolution. The small number of surviving paintings is due in part to Leonardo's habit of disastrous experimentation with new techniques and his chronic procrastination, resulting in many incomplete works. It is thought that he created many more works that are now lost, though records and copies have survived for some.

A commitment device is a way to lock oneself into following a plan of action that one might not want to do, but which one knows is good for oneself. In other words, a commitment device is a way to give oneself a reward or punishment to make what might otherwise become an empty promise stronger and believable.

A commitment device is a technique where someone makes it easier for themselves to avoid akrasia (acting against one's better judgment), particularly procrastination.

Wishful thinking is the formation of beliefs based on what might be pleasing to imagine, rather than on evidence, rationality, or reality. It is a product of resolving conflicts between belief and desire. Methodologies to examine wishful thinking are diverse. Various disciplines and schools of thought examine related mechanisms such as neural circuitry, human cognition and emotion, types of bias, procrastination, motivation, optimism, attention and environment. This concept has been examined as a fallacy. It is related to the concept of wishful seeing.

Some psychologists believe that positive thinking is able to positively influence behavior and so bring about better results. This is called the "Pygmalion effect". Studies have consistently shown that holding all else equal, subjects will have unrealistic optimism and predict positive outcomes to be more likely than negative outcomes. Research also suggests that under certain circumstances, such as when threat increases, a reverse phenomenon occurs.

Pornography addiction is the scientifically controversial application of an addiction model to the use of pornography. Pornography use may be part of compulsive behavior, with negative consequences to one's physical, mental, social, or financial well-being. While the World Health Organization's ICD-11 (2022) has recognized compulsive sexual behavior disorder (CSBD) as an impulse-control disorder, CSBD is not an addiction, and the American Psychiatric Association's DSM-5 and the DSM-5-TR do not classify compulsive pornography consumption as a mental disorder or a behavioral addiction.

Problematic Internet pornography viewing, also known as problematic pornography use (PPU), is the viewing of Internet pornography that is problematic for an individual due to personal or social reasons, including the excessive time spent viewing pornography instead of interacting with others and the facilitation of procrastination. Individuals may report depression, social isolation, career loss, decreased productivity, or financial consequences as a result of their excessive Internet pornography viewing impeding their social lives.

Piled Higher and Deeper (also known as PhD Comics) is a discontinued newspaper and webcomic strip produced from 1997 to 2021. The series was written and drawn by Jorge Cham, and follows the lives of several grad students. First published in 1997 when Cham was a grad student himself at Stanford University, the strip deals with issues of life in graduate school, including the difficulties of scientific research, the perils of procrastination, and the complex student–supervisor relationship. As of 2017, the strip's website had 6 million visitors in the previous year.
