It's What I Do: I Toke And I Know Things*

  I always find myself working along edges and in corners, where the Gotchas hide.

 I am a generalist and a synthesist, always have been, in large part to profound and mostly untreated ADHD.† I am the opposite of a Subject Matter Expert.  I have a tendency to start projects larger than my attention span, and subsequently lose interest in them.

 So the knowledge I have collected throughout my life tends to be all over the place.  I have always had a thirst for knowledge, and have been an autodidact my entire life.  If something piques my interest, I dive in headfirst and don't come up for air until I feel I've at least got a firm grasp on the subject.

 But long experience (I think it took me longer than most to figure this out) eventually taught me that having a decent grasp of a subject does not keep the Gotchas aways if you insist on working near edges and in corners.

 So now, I am actually more proud of knowing where the limits of my knowledge are, in most any subject I know anything about, than I am of what I know with certainty.  Because it is just as useful and important, but few people manage it.  Most people think they know more than they do.  I spent most of my life using that vewpoint.  But that viewpoint isn't baked into your brain.  You can change it. ;)
