It's sort of terrifying to think of just how much there is to learn about out there. While I teach I often find that even the subjects I think I know really well I barely know at all.
I wonder how long it would take to truly be an expert at something. And at that point since you're an expert, was it even worth it? I mean now you know all there ever is to know about sunflower seeds but you don't know shit about ice wedging.
I think I'm happy following in the path I'm in, knowing a tidbit of useless information about a variety of subjects. I'll be a professional surface skimmer for as long as I can.
