I was always impatiently curious, but abhorred school or being spoon-fed information not necessarily pertinent to what I wanted to know at any given time.
So, it was an obvious avenue; become a P.I. and get paid learning. It's what I always wanted to do.
A P.I. will eventually touch on just above every aspect of life, slice through a cross-section of society, most lines of work, every character under creation, and probably every situation or problem imaginable. It's challenging work.
