School of Hard Knocks
The School of Hard Knocks or University of Hard Knocks is an idiomatic phrase meaning the (sometimes painful) education one gets from life's usually negative experiences, often contrasted with formal education. The term is frequently misattributed to George Ade, but was actually coined by Elbert Hubbard in a piece he wrote on himself for Cosmopolitan in 1902. The term was re-popularized by the song "It's the Hard Knock Life" from the 1977 musical adaptation of Annie, which chronicles the life of poor, uneducated orphans. The song was also later popularly sampled in the 1998 song "Hard Knock Life (Ghetto Anthem)" by Jay-Z
It is a phrase which is most typically used by a person to claim a level of wisdom imparted by life experience, which should be considered at least equal in merit to academic knowledge. It is a response that may be given when one is asked about his or her education, particularly if they do not have an extensive formal education but rather life experiences that should be valued instead. It may also be used facetiously, to suggest that formal education is not of practical value compared to "street" experience. In the UK and New Zealand, the phrases "University of Life" and "School of Hard Knocks" may be used interchangeably.
