Your story is awesome. I just answer to say that I didn't like the "ordinary" you used to define your kids. Grow them not to be ordinary, even if they are just not ordinary to you.
But I've found I can reconcile that by switching a word: "Grow them not to be ordinary, even if they are just not ordinary to themselves". And that's probably what it should be anyway. I guess....
People are just people, but you can give the kids broad or narrow experiences.
Tell them about mountains, rivers and the seas. About different animals that they can't see anymore. Tell them about how mankind came to be.
You can be their, potentially, biggest inspiration at this age (presuming they are quite young).
PS: Sigh, I'm a hopeless romantic.
