For years I have been working on the premise that I might be ready by February, and that eased things up a lot. I do what I can, at a reasonable pace, now. House not as clean as you’d like it? Nobody actually cares. Behind on wrapping? Gift bags. Everybody has to work out their own issues with shopping, but I found that promises of a later event helps save time (a lunch out, a movie, a concert, something that takes place in the New Year).
I am stupid and goofy when I’m tired, so I just stop all the prep at a certain time of day, and relax. That’s how I do my “me time”.
Take it easy on yourself, if nobody dies, you’ve done a good job. :-)
