Recently, I've seen an awful lot of grumbling out there about the stress of Advent and, of course, lots of talk about taking the stress out of Advent. Frankly, I don't see where the stress in Advent lies. It's my experience that stress is usually found internally.
Regarding Advent activities... do what you want to do. We will always find time or resources to do the things that are most important to us! If something doesn't get done, well, frankly, it probably wasn't important enough. And that's OK! If it's not OK with you, then perhaps a reordering of priorities is in order, but only you can determine what your priorities should be.
The things I do are important to me and my family. The amount of effort I put forth is directly related to how important it is to us right now. Years ago, when the kids were littler, different things were more important so we did those things. Years from now when my kids are older, I'm sure new things will take primacy of place on our Advent to-do list. We don't try to do it all.
I was talking with a friend a few weeks ago about her family's Oplatki tradition and tears welled up in her eyes remembering the warm feelings that this tradition inspired. It was truly moving, but they were her feelings, her memories, her traditions, not mine. I didn't feel the need to insert this foreign-to-me custom into my family's practices, even though I might find something intriguing or inspirational in the idea of it. There have been occasions when someone else's tradition stirs up excitement and interest and so we try it and find that it suits us, so we keep it.
I've read people's musings on how no Christmas music will cross their eardrums until Dec. 25th; Advent hymns only, please! And I think... well, that would require noise canceling headphones for everyone in the house since our piano teacher starts handing out the Christmas sheet music around the end of October. Obviously, that kind of Christmas music banishment isn't going to work in our family, but it might be just the thing someone else needs to set the Advent mood in theirs. (Listening to Carol of the Bells practiced twenty thousand times in the months leading up to Christmas really emphasizes the "preparation" aspect of Advent, if you ask me.)
Learning to admire something without feeling pressure or guilt takes effort. It doesn't just happen. And some things are worth working on, if they are important enough.
