Do what one will to maximize ones own sense of overcoming mundane life.
I understand their ideas about the situation were meant to prod people out of their mundane lives. The situation being, IIRC, a construct of the activist which itself has no workable definition.
IMO situationism then, failed when the May riots did, on the grounds that this artistic movement could only be gauged on its supra artistic revolutionary success, or lack of.
So my formulation is broadly situ like, but more individual, and more resigned.
