What do I do in survival mode?

So I’ve recently picked Minecraft back up. It had been a few years and I started a new survival game.

I have a house with a huge basement for storage, a farm with wheat, sugarcane, potatoes, melons, pumpkins, and carrots, and it’s also got some animals on it. I just made a huge strip mine and got a bunch of diamonds, so I made a nether portal, but I don’t really know what else to do…

I have a good base, got diamond tools and armor, and have a ton of food, is there anything else I should do, because I don’t know where to go from here.

Thanks!
