There are some things that I've noticed that I do every time I start a new world in Minecraft. Here are 4 of them
Find the Nearest Village
Gamepedia
Every single time I start a world that's not a super flat world, I always find myself looking for the nearest village, which brings me to #2----
Steal Stuff from the Village Chests
Youtube
There's some pretty good loot in those chests if you know where to look (blacksmiths and the like have the best goodies)
Tame Wolves
All the dogs. ALL THE DOGS!!
Tame 5 Horses

Don't know when I'm going to use the other 4, but I want them
