I’ve been feeling tired lately. Not the usual “I’m a bit underslept” tired, but deep-in-my-bones tired. Soul tired. People who know me will say I’m a naturally motivated person (I mean, they won’t, but they might think it). I’m very productive and want to get shit done. I rarely meet my own standards for productivity on any given day, but my wellspring of motivation is deep. Even outside the PhD, I get satisfaction from doing things well (poetry, calligraphy, dishes) so the motivation flows. I feel incredibly lucky that this motivation is reliably present. If I'm tired, a few hours of relaxing – maybe up to a day or two – will make me antsy enough to get back to work. But for the past few months, my motivation has run dry. I’ve been feeling too tired to want to do things...
