Best advice I received: imagine you&#x27;re going to be on the plane for the rest of your life. Don&#x27;t watch the clock.<p>I constantly underestimate the temporary IQ loss from altitude and jet lag. Bring light entertainment. Comedies, tell-all or humor books, documentaries. Do not attempt to read Douglas Hofstadter on a plane. And don&#x27;t bring Game of Thrones in case the person next to you (a) isn&#x27;t into it or (b) is trying to avoid spoilers.<p>Played correctly, I am mildly disappointed when I have to put things away for the landing.
