Anyway... veering away from Danoff's asertions that you should just work like a slave and nothing else your entire life, because otherwise you might miss out on a bit of interest:
There is a great big wide world out there, full of fascinating sights and people and I, for one, want to see more of it. I've travelled a little bit over the last couple of years, mostly around Europe, but also to the US, the Middle East, and two all too short visits to the Seychelles and Cuba. But now I want to experience a lot more - I want to go to the far east - places like Thailand, China and Vietnam are calling to me. I'd love to see a good bit of South America - a few friends trekked the Inca Trail a few years back and loved it. And I want to see more of America.
I'm a little bit stuck at the mo, having a 6 month old daughter and a good-sized mortgage, but once the kids are a little bit older, I'll be heading off out there again. I like to think that I'm a more rounded and slightly more, for want of a better word, wise person for having experienced different countries and cultures. And I will encourage my kids to get out there a bit when they're old enough.
The OP mentioned that they'd never been outside Texas. I find this really weird, not least because I'd been to Greece, France and Spain before I was 4. I just don't understand how, in this day and age, with all our access to easy world-travel, that anyone in the first world has enevr been out of their immediate vicinity. Get out there, see some stuff, have some exeriences, you'll be a better person for it. Even if you don't leave America, there's a lot to see without having to leave your own borders...
