If you have Morrowind or Summerset, it puts you into those locations first. I recommend going back to the base game starting location, I think this is;
AD: Grahtwood
EP: Mournhold
DC: Wayrest
enjoy the questing and take your time. Eso is not a typical MMO where you are meant to rush to max level.
I'd also recommend learning the traits of anything you can, as this process takes forever. When you have an item with an uknown trait, go to a crafting station and learn the trait. This will deconstruct the item.
Lastly, level up your mount each day at a stable, as this also takes ages.
I didn't even know you could do that level up your mount I mean, I have only just started playing the game.
I agree with the going back to the starting zones it makes the first level's go much faster
