In its original sense, discipline is systematic instruction given to disciples to train them as students in a craft or trade,or any other activity which they are supposed to perform, or to follow a particular code of conduct or "order". Often, the phrase "to discipline" carries a negative connotation. This is because enforcement of order – that is, ensuring instructions are carried out – is often regulated through punishment. Discipline is also believed to be one of the main pillars of modern life, according to many different religious beliefs.

Military discipline refers to the regulation of the behaviors of members of any military, involving rules that govern goal orientation and behavior inside and outside the institution, including the socialization processes that happen in military training Rules of discipline are firmer or laxer depending on the prevalent culture of the military's country or institution. As early as the time of the Roman Army, discipline was enforced through military justice, but broader compilations of laws such as the Codex Theodosianus contained provisions dealing with military discipline.

Napoleon Hill (October 26, 1883 – November 8, 1970) was an American author who was one of the earliest producers of the modern genre of personal-success literature. He is widely considered to be one of the great writers on success. His most famous work, Think and Grow Rich (1937), is one of the best-selling books of all time (at the time of Hill's death in 1970, Think and Grow Rich had sold 20 million copies). Hill's works examined the power of personal beliefs, and the role they play in personal success. He became an advisor to President Franklin D. Roosevelt from 1933 to 1936. "What the mind of man can conceive and believe, it can achieve" is one of Hill's hallmark expressions. How achievement actually occurs, and a formula for it that puts success in reach of the average person, were the focal points of Hill's books.

According to his official biographer, Tom Butler-Bowdon, Napoleon Hill was born in a one-room cabin near the Appalachian town of Pound, in Southwest Virginia. Hill's mother died when he was eight years old, and his father remarried two years later. At the age of 13, Hill began writing as a "mountain reporter" for small-town newspapers in the area of Wise County, Virginia. He later used his earnings as a reporter to enter law school, but soon he had to withdraw for financial reasons.

The Cure are an English alternative rock band formed in Crawley, West Sussex in 1976. The band has experienced several line-up changes, with frontman, vocalist, guitarist and principal songwriter Robert Smith being the only constant member. The Cure first began releasing music in the late 1970s with its debut album Three Imaginary Boys (1979); this, along with several early singles, placed the band as part of the post-punk and New Wave movements that had sprung up in the wake of the punk rock revolution in the United Kingdom. During the early 1980s, the band's increasingly dark and tormented music helped form the gothic rock genre.

After the release of Pornography (1982), the band's future was uncertain and Smith was keen to move past the gloomy reputation his band had acquired. With the 1982 single "Let's Go to Bed" Smith began to place a pop sensibility into the band's music (as well as a unique stage look). The Cure's popularity increased as the decade wore on, especially in the United States where the songs "Just Like Heaven", "Lovesong" and "Friday I'm in Love" entered the Billboard Hot 100 chart. By the start of the 1990s, The Cure were one of the most popular alternative rock bands in the world. The band is estimated to have sold 27 million albums as of 2004. The Cure have released thirteen studio albums, 10 EPs and over thirty singles during the course of their career. Since 2010, they have been working on a fourteenth studio album.
