As a kid, I wanted to be a Jedi  that was the ultimate goal. To find out you could move stuff, to find out that you were more than you thought, that it was something inside of you. It just spoke so clearly to what we're all looking for: You wanna be special.
I feel like the series was about becoming the best you can be as a person, being something special  even more so when you feel like you see something reflective of yourself. So what having John Boyega at the center of The Force Awakens does for future generations, in terms of how it affects them, is amazing because it actually puts them in the story in a much more layered and intrinsic way.
Seeing that black people made it to space was big. But Lando Calrissian was 
 I mean, I love Billy Dee Williams, but he was basically a space hustler. "That's the character that we get? We get the space pimp?" But I thought the casting of Boyega as Finn was a huge leap forward, not just in terms of diversity, not just for black and white, but looking at our world that we live in today, that we're all a part of it, and we're all sort of part of a joint ecosystem. I look at the casting, and it's exciting to me.
