Daydreaming and lists are a big one for me, too! I don't use spreadsheets much, though sometimes I've used them to keep track of character details so I can quickly check out everyone's appearance, age etc. But I haven't done it for my recent projects. The zero drafting you speak of sounds interesting - if my current methods don't work as well as I hope, I could give that a try.

Woo, yay for some ideas for the steampunk novel! Good luck with your packing and moving, it's quite a task so I'm not surprised if it's hard to find time to write while that's going on.
