Leg Day

"Rey is so good at everything that it doesn't even make sense. How can she use the force so well without learning anything? Stupid. I'm not sexist. You're the one who brought up gender."

I don't know, ask Luke. He used the force to change the course of his torpedos in the first movie, and force pulled his lightsaber in the cave before ever meeting Yoda. Why is it so hard to believe that Rey knew how to fight, and also had a solid understanding of mechanics when she's spent her entire life on her own, scavenging through crashed starships? Why would she carry that staff with her everywhere if she hadn't trained to use it at some point? And in The Force Awakens, we clearly see she knows how to fight when she takes out the thieves trying to take BB8.
