My chapter proposal has been accepted for inclusion in a book now what?

So I just heard my nonfiction chapter proposal for a book has been accepted, however, now they (the editors) have to make sure the publisher is onboard with the whole idea of the book. It’s another hurry up and wait time, so I think I will let my brain start formulating ideas on what I will write in that chapter drawing upon my proposal.

But wait! When I look at my calendar I see next week is chockful of activities. Tomorrow and this weekend may be the lull before the storm. I’d better get organized and start putting my ideas on paper so to speak, prior to Monday! Between workouts, babysitting and traveling next week there may NOT be much writing time. I know I can’t write when I travel (can’t read much for that matter either since I am a lousy traveler) so I know better than to try.

Any advice? What would you do? Do you have similar experiences to share? Feel free to comment below.
