Quantified self describes a method of recursive self-reflection through making visible what was formally invisible through the normal observation of everyday life. A cybernetic feedback loop where one can see the effect of something over a long period of time by taking measurements at an interval.
Known versions of a quantified self are Feltron's Annual report, personal wearable pedometers, Aaron Parecki's 3.5 years of GPS data, and Will Wright's SIMs game.
