Yesterday afternoon, I listed everything that's left to do for the party, up to the point on my Big Day list where we get 16 bags of ice from the store.
The whole list came to less than half a sheet of notebook paper. Pretty cool!
Because we're doing our own cooking instead of having the party catered, I plan to finish all non-party tasks by Wednesday before the party. That way, I have three days devoted to just one thing--prepping food--and the rest of my life does not have to fall apart as I prepare.
Let me stress again that I could not do this without a system. Systems are miraculous.
