Yes, don't get me wrong, I think it's great to have early retirement as a goal, and maybe even try it out for a while (it was my goal from an early age and I tried it out for three years in my late 20's / early 30's). It's excellent motivation to save money when you're starting out.
And I was in the same boat; when backpacking through Thailand I thought, "Thailand is cheap, I'll just raise a family here". Well sure, for backpackers it's easy to live on 3K per year. But with a couple kids, you'll likely want a safe car (stupidly expensive there), decent schools (again), something nicer than a backpacker hostel, etc. Heck, flights home to visit family will run close to 10K per year alone.
