I worry a lot, about all kinds of things. Over the summer, herself said to me, “That’s a problem for today.” “What?” I said. “Well,” she said, “tomorrow, that won’t be a problem because it has to be dealt with today.” Although, obvious, like all self-help advice, it’s a formulation that works well for me. “A problem for today,” I mutter to myself as I deal with my nasty head cold, a dull meeting or whatever it may be. I offer it here for free because I’m generous that way.
