The “dream” is the result of a lot of hard work and sacrifice, and like Foxhunter said, it takes a lot of work to maintain! There’s nothing saying you can’t have that in your own country, but you have to play the game like everyone else. I will be 32 in less than 3 months and still chasing my own dream after some hefty setbacks, and I was born right in America's capital!
If you want a house, kids, dog, what-have-you, your best bet is to learn all you can now about how to manage your finances. Finances and learning to manage a home and bills are the cornerstones of actually getting to live those dreams. Read books, find free seminars to go to about managing your money, and look for a career that makes a good living. Learn to live within your means and not stretch yourself to the limit. Find out what your credit score is and how to keep it healthy! Finances keep a lot of people from achieving their dreams, or delays them until very late in their lives.
Sitting around and crying for what you want in life does nothing to help you get it. I have days where I feel like everything I want is very far away, but we build the future one day at a time!
