There are days when you need ferocious action, and there are days when you need a new detective story and a chocolate.
And, I would add, there are days to be grateful for the tiniest hint which is which. Need states are partly fact and partly fiction, which makes them hard to figure out.
Practice: Identify a small step that feels like it could clarify what you need. Write one blistering letter (you don’t have to mail it). Take one bite of chocolate (it needn’t contain sugar). Take action, but keep each step small. Repeat until you have done something that, in retrospect, turned out to be nourishing.
