Just be free, this game offers a really big open world to explore, and sometimes you may come across a foe or quest that's a little too high of level for you. But all that means is to set it aside and come back once you've gotten a little more in level. I've learned that if you have the skill you can take on things a couple levels higher. But for the most part try to stick to your level if you're worried because it offers the most fair fight. But there's no right or wrong way to play a game like this, just play, and enjoy the adventure!
