I often wonder why the thought of moving somewhere far away is appealing to people. Leaving all this shit behind etc.

I've been there. Traveled for many years around asia and south america, worked (fulfilling?) volunteer jobs etc.

Then I returned home. Fixed all the shit I left hanging here and started to live a decent life right here.

The answer I've found is that only people who haven't been travelling, dream of travelling. Those of us who've been there, know that it's not very appealing if your mind is troubled. Your life won't magically change if you move to another country.
