First you need to get some wood, you should get around 32 to 64 blocks of wood. Then make a crafting table along with a house and a furness. Try to make a few tools and make coal. Or charcoal if you cant find any. Make a bed next, and then a mine. Its good to make the entrance/exit to your mine in your house so you dont need to make a mad sprint to your house. Next make stone tools. Upgrade your house alot and your tools. Make a farm and a animal one too! You breed them. And you kill them too.
