Well, it's finally after thanksgiving, which means we have a month until Christmas, Hanukkah, Kwanza, and all other sorts of denominational/non-denominational holidays roll around. Either way, there is now a variety of things you can do to get into the holiday spirit that are now officially socially acceptable (it is after Thanksgiving, after all.
Play ALL The Holiday Music
No one can judge you at this point for listening to holiday music. Or winter music. Or anything that is remotely related to snow (I'm talking to you, "Sleigh Ride"). Even so, it's pretty hard to be mad when you're listening to anything as cheerful as most holiday music. So pick your favorite songs (I prefer Pentatonix's Christmas albums) and go nuts.
Decorate the day after Thanksgiving (or sometime soon)
Nothing gets you quite excited for the holidays like decorating. It's a perfect excuse to spend time with your family and other such loved ones. Also it makes the place look nice and festive. Another good excuse to play holiday music. Also more fun than leaving everything up year round
Go Holiday Shopping
This one is pretty self explanatory. It's also pretty fun to see what all they different stores look like decorated. Or how beautiful your decorated living space is if you shop online. Also saves you fewer weird looks
Go to a Christmas Tree Lighting
It's mostly just really pretty. Especially in cities like Boston and New York City.
Buy a giant stock of hot chocolate
Bonus if it's peppermint hot chocolate. This is more for the cold days in the coming winter where you don't want to go outside but also want something warm. The same thing applies for festively flavored instant coffee.
Start a count down to your favorite holiday
Why not.
Enjoy the snow
Snow is pretty for a while, we all have to admit that. Instead of worrying about the constant cold for the next few months, go out and start a snowball fight. Or make a snow angel. Or build a snow fort and hide in it.
Spend time with your friends and family
This is the one time of year where you have free time so use it wisely.
Or be antisocial and watch every single holiday movie on Netflix
You don't have to be social if you don't want to. But I highly suggest "A Christmas Story". It's hilarious.
Get an ugly Christmas Sweater
It's the best time of year to wear an ugly sweater. Treat yourself.
