Laziness
Laziness (also known as indolence or sloth) is disinclination to activity or exertion despite having the ability to act or to
exert oneself. It is often used as a pejorative; terms for a person seen to be lazy
include "couch potato", "slacker", and "bludger". Related concepts include sloth, a Christian sin, abulia, a medical term for reduced motivation, and lethargy, a state of lacking energy. Despite famed neurologist Sigmund Freud's discussion of the "pleasure principle", Leonard Carmichael noted in 1954 that "laziness is not a word that appears in the table of contents of most technical books on psychology". A 1931 survey found high-school students more likely to attribute their failing performance to laziness, while teachers ranked "lack of ability" as the major cause, with laziness coming in second.
