abstruse \ub-STROOSS\ adjective

I took a train ride today- my second of what will be three this week- which always gets me thinking.  about things.  And stuff.  And usually other stuff.  There are many things that I don't understand fully, but I've noticed that more & more, I'm really fine with it.  I certainly always seek to learn & grow, but at the end of the day, I feel like all of life's little mysteries should be difficult to comprehend, to an extent.  That's what prompts the need for art.
