Eh, the insomnia is what it is. I manage it, albeit not well sometimes.
It is a big log! About 3' long and over 1' around! The whole day is a journey - in the morning we rise at dawn to bless the log and reflect upon the old year that's now passing. It's a moment of sober reflection - of both good and bad - and a moment to acknowledge what our needs are and how we can be better the next year.
And then, well...

Actually presents and food are a big part of the deal for us - I have been carefully selecting and making presents for a month or more. But there's a reason for it. You're expected to share your generosity around the winter holidays (when times are grim for many) and bathe the people you love in your excess. It's all about giving back to the people you love and who have less out of love rather than obligation. If you can't give back, you're not obligated - it's specifically about sharing love and bounty and well, if you don't have bounty that's OK, that means it's more important to share ours with you. We are generous on Yule because the world has been generous to us. A lot of the gifts we give are hand made and specifically wanted and useful - not just "stuff" of obligation. Same with the feast we usually hold for our friends. It's also encouraged to give to charities that help people who are down on their luck without judgement - food pantries are usually an ideal choice - and be kind to animals and wildlife on this day. My faith has a lot of traditions rooted in things like that.

Giving back is important - especially within your immediate community and environment. It plants the seeds for a better future.
It also carries an additional goal to have a big party like that - to spread joy on earth and make the world so happy that the sun WANTS to come back.

In a hurry! For just a bit you live only in the moment and just be as happy as possible! This year we went wassailing at our friends houses and leaving them gifts. <3 It was super great to see all their faces. I was so happy! Then I held a videochat party with a bunch of them! It was so nice! I think we all left today feeling much happier and a little more hopeful for the new year.
And now it's the long vigil, where I think about how grateful I am for all the people I got to celebrate with and how life will be different next year and what our plans are and what we hope will pan out while I wait to see if it worked and we were joyful enough for the sun to rise again.

(Of course, we do a good job so it always does.
