I know I am in the right field because I see the things I do as uncomplicated and obvious, while others apparently see it all as incomprehensible and interminably difficult. (I work in infrastructure, mainly.)

Whereas I see programming as just a slog and a huge mess of unfathomable code and weird characters used inexplicably and apparently at random. Though I do near-programming (lots of scripting), I will never like it and do the bare minimum possible for my career.
