I've always been fascinated by computers.  I learned on a Commodore Pet prior to buying my first computer, a Commodore Vic20.
The fascination with data and databases comes from the ability to predict behaviours from data and measure the results of attempts to influence those behaviours.  I am Aspergers so a vague clue as to the thoughts of neuro-typicals reduces the faux-pax count a bit.
You could say that I am intrinsically motivated.  However, some data technologies I have to be extrinsically motivated, particularly those that allow or even encourage the sullying of data.
