I think when these things are thought of in terms if what you “could” do or “should” do then they become very difficult to solve, because there are so many points of view and no real crystal ball.
However, if your think in terms of what do you “want” to do, it sounds like you already have your answer. Follow your passion and let the rest fall to the side.
My question is, you seem very passionate about this, why would you want to only do it for one year?
