To be fair, Thanksgiving doesn't have much competition. Most other holidays have some sort of random thing you need to wear or buy which is kind of annoying. Things that are great about Thanksgiving:
1) Food. Now turkey isn't the best meat on the planet... but enough gravy and sides make it palatable. My favorites are actually some of the food that comes after Thanksgiving day. Turkey Soup and "Slop Plates" which are basically just everything from the meal mixed up with gravy on top.
2) No gift buying! The pressure of how much to spend and how thoughtful your gift is... causes me a lot of anxiety because I am typically a bad gift giver.
3) No stress. Everyone is happy and thankful. It's just a good atmosphere all around.
4) The Cowboy always play (and usually win)! I've been a Cowboys Fan since youth.
I have a lot of things to be grateful for this year. I've had a lot of fun with my new hobby. Got to travel to Iceland/Paris/Germany (Blog post coming soon). Work is going well (got to go to a sweet conference and got a substantial raise). My friends and family are in good health. Life is good!
