I don't understand what to do

I'm a new player to eso and I've been playing the game for at least 5 hours and I still can't understand what to do. The quest's kinda made me curious about the canonical way to play them because I didn't get most of the things I've seen. Also I don't even know what to do except the quests. Can somebody help me understand how to play this game cause it's too complicated for me ig.
