the force allows for a natural affinity to use it.

Before Anakin was even trained he was showing a strong ability to use the force. He had heightened reactions, he was having visions of leaving Tattoine and returning.

You have to wonder about Jedi Training. I don't know if its as much Jedi Training as much as giving them some lessons on how to feel the force, and swinging a stick around. And then you basically find your own way.

Qui-Gon and Kenobi didn't share the same affinity. Obi-Wan didn't have the ability to tap into the force to see the future like Qui-Gon did.

Kenobi and Anakin were the same thing, I doubt that they trained Anakin as much as they tried to control him.

When Luke went to see Yoda, it wasn't as much training or swordsmanship as it was trying to teach Luke to tap into the Force and lose him impulsiveness.

I remember reading a interview with Lucas when he talked about the PT and he said that the one thing that he wanted everyone to see and understand was what a fully trained Jedi could do. But he also hinted that the way a Jedi used the force needed to evolve, but the Jedi were so locked in their way, grabbing babies, training them all the same way etc was doomed to fail. They were training Jedi to fight a war from a 1000 years ago, meanwhile the Sith evolved in their training as they worked to gain a better understanding of the force and what it could do and because of that they destroyed the these fully trained Jedi.

Luke then screwed things up by trying to go back to formalized training.

With Rey, he gave her the formal ability to touch the force and feel it, the rest she's going to have to figure out on her own and decide where her talents lie.
