1) Barf forth more apocalyptica. It gets to the point where I peek down at my MC sheet and see it there, and I go, "Oh yeah, need to do that." Same with "digressing occasionally."
2) Coming up with interesting things when a player misses an Open their brain roll. This one always kills me. I'm there with a blank look on my face, trying to find something to best represent the maelstrom and to be suitably weird / interesting.
3) Sometimes, I don't throw any new NPCs out there for a while! My 1st Session sheets tend to be kind of empty. And when we finally get rolling, I play the NPCs already established and rarely introduce more.
