[E]verything was much harder to do than I imagined, despite the fact that I was already imagining everything would be much harder than I imagined. I mean, I began from how hard I thought everything would be, multiplied this by the usual you-know-things-never-go-as-planned factor, then multiplied this by a no-seriously-it’s-going-to-harder-still factor, and still came nowhere close to imagining the horrors ahead.
