A metaphor is only supposed to go as far as it’s supposed to go

Here’s the thing about using metaphors: They are only supposed to go as far as they’re supposed to go.

They have very short communicative half-lives.

If you cook them too long long, they end up being dry.

There is only so much blood in the metaphor turnip.

I know we like to be clever, but, too often, we draw out and extend figures of speech when talking about important things. Almost every time, what results is just a muddying of the waters. It’s sad really. It’s like we are fundamentally incapable of seeing the forest through the trees.
