^^ Unless you do it today, you have waited until December!
My tree is a "family tree". My mom and I have both given my kids ornaments through the years and we have also bought a lot of them on vacations. They have sentimental value and meaning. The kids have made a lot of ornaments too. We each have a bag of our own ornaments. Admittedly, most of mine are squirrels or red, buff and green (or are actual Alpha Gam ornaments). I fill in around those ornaments with a few bows (red) and some antique bulbs from my mom (which were from her mom/my grandma originally). Almost every ornament is meaningful to us. I think of it as a tree of love
I usually decorate over Thanksgiving weekend but with school demands this year, it isn't done yet. We are going to try to get the tree up tonight if we can. In addition to the tree, I have a beautiful lighted garland for the mantel, Santa Bears (yes, I'm showing my age) that sit on the hearth, numerous Christmas music boxes that go in the curio cabinet and on shelves around the house. I have all kinds of things like that, for the shadowbox in the kitchen and some things for the bathroom even. I love Christmas decorations

We have an entry table where we set up the Nativity scene and a special shelf for a Christmas village that my aunt gave me. Love it all
Outside, I put lights on the gutters and shrubs and have two lighted spiral trees and lighted gifts that go under them. I am having all of my shrubs cut down on December 9th though, and need to have the gutters cleaned right after that so I don't know when that will happen this year, if at all
