I actually read your post yesterday, and it has been stewing in the back of my mind all day today. Here's what I think: Don't give up on your dreams! Sometimes, it is not the actual fullfillment of the dream that makes life wonderful, but the pursuit of the dream itself. My DD loves the movie "Up", and if you haven't seen it, that is the whole theme of that movie. Sometimes, the realization of a dream is not as wonderful as the life you live while pursuing that dream.
And who knows, maybe one of the little ones you are nurturing now will grow up, buy a cattle ranch on thousands of acres somewhere warm (I'm thinking Texas), and build you a little off grid retirement home there so you can be close to your grandchildren. As long as there is life, there is a chance to fullfill your dreams.
As for those people who are fullfilling their dreams at an early age, just think -- what are they going to long for next? Because isn't it true that most of us have a dream that is beyond where we are now? Maybe in a few years you will reconnect with that person that acheived those dreams that you have, and discover that she is not all that much happier than you are in your life.
It's all a balance. I, too, would love an off-grid house in the countryside, but I would trade it in a second for my DH and my DD. They are true joy, more than any material thing. But that doesn't mean I give up my dreams! My husband jokes that our current house is a 10 year house, the next house will be a 20 year house, and then maybe I can have my "dream" house. (Note that in 30 years my kids should be grown, maybe with kids of their own, and I should be (hopefully) ready to retire and collect a pension.) In the mean time, I'm happy with my veggie garden, decent house, and happy family. Yet I still say things like "when we build our house, it is going to have the best windows we can get so that it stays warm in the winter!" Of course, in 30 years when I'm building my dream house, maybe I won't be moving someplace that HAS winter. Ha!
I hope the weekend brings you some joys in your life, and that you either have some new dreams develop or decide to maybe allow those old dreams of yours to continue to simmer in the back of your mind. As a final thought, for the record, I think your dreams are perfectly reasonable. I mean it's not like you're saying you want to be a billionare with a private plane, or that you want to win an Olympic medal for gymnastics. Maybe they won't come true in 5 years, or 10 years, or even 20. But who knows what surprises the future will bring?
