have to vs get to

I don't know who said it anymore - not sure it matters - but when asked Why God created the world, they answered something along the lines of "for us to enjoy it". 

That's why. To enjoy it. What a concept. 

I was with a college freshman who said that everything changed in his first year of school when he remembered he didn't have to be there. He wanted to be there. He got to be there. 

You don't have to do that. You get to... enjoy it.

That alone, might make some decisions for us.
