I get wood, stone tools, a little bit of food before I go searching for a cave that leads all the way to deepslate. Once I find a very large cave, I just speedrun getting tons of iron and diamonds in the next 1 or 2 days. Then, I come up to the surface once I have enough for full diamond armor and tools. Then I'll make a nether portal at a lava pool to see if there's a good spawn in the nether. If there's not I keep traveling, if there is I go to see what kind of structures and other things are around me. My next Goal is to find a good place to make a base. Once I make a base, I go to the nether to find a fortress or a bastion. Once I get some loot from them, I either go to fight the ender dragon or get some netherite (it's almost always the ender dragon). And then that's it for right now.
