Do it yourself (DIY) is a term used to describe building, modifying, or repairing of something without the aid of experts or professionals. The phrase "do it yourself" came into common usage in the 1950s in reference to home improvement projects which people might choose to complete independently.
In recent years, the term DIY has taken on a broader meaning that covers a wide range of skill sets. DIY is associated with the international alternative rock, punk rock, and indie rock music scenes; indymedia networks, pirate radio stations, and the zine community. In this context, DIY is related to the Arts and Crafts movement, in that it offers an alternative to modern consumer culture's emphasis on relying on others to satisfy needs. The abbreviation DIY is also widely used in the military as a way to teach commanders (hence how from this YouTube videoclip) or other types of units to take responsibility, so that they'd be able to do things themselves just as a preparation for their own future.
The DIY movement is a re-introduction (often to urban and suburban dwellers) of the old pattern of personal involvement and use of skills in upkeep of a house or apartment, making clothes; maintenance of cars, computers, websites; or any material aspect of living. The philosopher Alan Watts (from the "Houseboat Summit" panel discussion in a 1967 edition of the San Francisco Oracle) reflected a growing sentiment:
Our educational system, in its entirety, does nothing to give us any kind of material competence. In other words, we don't learn how to cook, how to make clothes, how to build houses, how to make love, or to do any of the absolutely fundamental things of life. The whole education that we get for our children in school is entirely in terms of abstractions. It trains you to be an insurance salesman or a bureaucrat, or some kind of cerebral character.
