Give the player goals. Or let the player choose from a set of goals. And then tell the player how far along they are in reaching those goals.
It makes for a better game if the player is working towards a goal, and understands how far away that goal is. So, it’s better to put important bits of story that the player is reaching for in Always storylets, so that the player will be able to see that they need only 4 more points of Investigating the Broad Street Murders to see the next bit.
You don’t have to treat every story in your world this way. It can be good to have occasional surprises or a story that can’t be advanced at will in Sometimes decks. But most often you’ll want players to be able to see where they’re going.
