Talk - Action = Shit. AMEN
This is implying, though, that “action” is a part of “talk” that can be taken away. (And you’d be left with the resulting equation: Talk = Shit + Action .. which makes no sense.)
Instead, I think of it as a giant universal set sort of thing, with both talk and action in it. The set just then becomes shitty when the action is removed from the set, and all that’s left is the talk.
