When it comes to parties, I think breaking down tasks and being super prepared is important. The more days over which you can spread the work, the better. For example, I COULD get ingredients for, make, chill, and decorate a cake all in the same day I'm going to serve it… but I'd probably sacrifice a lot of other tasks to get there. Being organized and practicing foresight are key. And don't be afraid to delegate tasks to others.
I think this question is less addressing time off, but I do want to say a few words. When you make your own schedule, it's important to maintain consistency, if possible, and a bare minimum of foresight if not! Plan backward from deadlines and things that HAVE to get done.
Oh, and good luck 🙂 you've got this!
I recognize that I get less done this way, but the bowl of my mind must be empty, before I can refill it.
