Worrying that every move that you make and every breath that you take affects the cosmos is pointless. On the other hand, once the thought has settled into a crease in one of the lobes, how do you forget about it? If I leave the house five seconds earlier or five seconds later than I planned every molecule, each electron, all elements will have everything changed.
That's a lot of responsibility. I think I'll just take my clothes off and lie here really still. Maybe I should have a glass of wine.
