Not a real medical condition.

But one that arrives every time before I travel.

What books should I bring? How many books? Am I bringing enough books?

What if I run out of something to read?

This problem should be solved by having a store of books on my phone. But there is something reassuring and comforting about having a thick paperback in hand when boarding that plane.

But what if the book is a miserable experience? Or if I read through it too fast?

Inevitably, the night before I travel, I have half a dozen books piled up. How heavy is that carry on going to be? Time to parse.

One book, two, three?

And how many times have I returned from a trip only having read fifty pages of one of the three books?

Better safe than sorry.
