The visible reminder of Invisible Light.”
~ T.S. Eliot, Choruses from The Rock
The problem with waking at two in the morning is not, necessarily, the waking, but the assumption that it is too late to rise for the day and, instead, opening up one’s Kindle and reading for an hour or so then falling back to sleep.
Sure as the sun rises, this will result in one sleeping in long past the desired early morning waking hour and the day, and the week, will get off to a discombobulated start.
