There are photographs of you from ten years ago that you disliked at the time.
Look at them now and they mostly seem fine. Better than fine, one or two of them. Whatever you were seeing back then wasn't in the picture at all; it was in the looking.
You are standing inside that same gap right now. In another ten years this body will be the one in the photograph somebody wishes they had appreciated while they had it.
Which is why the acceptance has to be dated. Not the body you had at twenty-two, not the one you're planning for by spring. The one currently reading this, at whatever weight it is, with whatever ache it woke up with.
