Your main goal should go in some sort of order like this:
Get Shelter/grab food (killing animals, etc) > Create Bed > Create Tools/Camp/QoL stuff (ie, chests for items, crafting table, furnace, etc) > Obtain/start growing food > Capture animals to start a small farm > Begin mining [As you mine, your garden/animals will grow so you have a constant food source] > Obtain Mats and continue upgrading gear/tools/armor [At this point, you can wander around the world too and try to find overworld resources. If you have another player with you it gets much easier because you can split up and explore/mine/garden but otherwise as a single player this works best] > Eventually make portal to Nether >obtain mats for strongest weapons/enchantments, etc > eventually make End Portal or find it >Battle Ender Dragon
I've logged hundreds of hours and sometimes don't come anywhere close to getting to The End. And of course you can always come back, just make another world to explore or start over again if you feel sluggish at some point. At any point in there when you have time, you can also choose to "beautify" your camp. For instance, stair pieces look like chairs when you set them out, you could build yourself an actual nice house out of wood or cobblestone, make paintings, etc)
