I have interests that are outside of everything I do, including the movies, so I have other things that I want to do,» Costner said about when he'd be ready to step outside the  universe.As far as what's next for him, Coster said there's still a lot he needs «to learn.»«I just feel like, listen, when I was younger, I grew up in such a conservative way.

I actually thought the world was flat,» the 67-year-old actor admitted. «I mean, I didn't know what was possible for me -- I came up with a really good foundation, but I I thought there was a lot that I needed to learn.

There's a lot that I still need to learn.»Costner continued, «I mean, what I will regret when I do leave, shuffle off, you know, it's probably books I'll never have read, and songs I'll never have heard, the stories.
