I was inspired to enter the micronational world after discovering Molossia in 4th grade. I have no plans to leave.
The final inspiration was, of course, Flatland and the YouTube sector when it was alive.
But, before that, I belive I knew Sealand, my dad's micronation (well, not entirely a micronation, it was never properly established or anything), and my geofictional nation, Yugoslavia (I had no idea what was it back then, it's really long time ago).
