Find a server with daylight (you can filter "daytime" or "24/7" usually those servers are daylight servers). Now, expect to die a lot until you learn the game. Don't let it get to you. Eventually you will become a GOD AT THIS GAME. Also, find a shirt, and right click on it in your inventory. Then rip it. Now you have bandages. Also, eat and drink everything you find until your stomach hurts. Never hold onto food or water unless you can't eat or drink any more. Consume it all.
