As a fairly dedicated hermit, provided you aren't within a one hour radius of Reykjavik or Akureyri, you could easily live the dream life. I had a hard time tearing myself away after seeing all the faces of the country in a short period; it was a whirlwind of every conceivable type of weather and landscape all at once and I really appreciated that experience. You could absolutely imagine traveling from world to world rolling down the empty highway. Highly recommend shoulder season!
