Hack

Life hack (or life hacking) is any trick, shortcut, skill, or novelty method that increases productivity and efficiency, in all walks of life. The term was primarily used by computer experts who suffer from information overload or those with a playful curiosity in the ways they can accelerate their workflow in ways other than programming. The terms hack, hacking, and hacker have a long history of ambiguity in the computing and geek communities, particularly within the free and open source software crowds.
