Im know what you mean Rhun, I find "far-away" places a bit daunting.

You develop your own network at home, you become reliant on your own system of people, routines and resources.
Breaking from that network is daunting, but once you do you just replace it with another network adjusting to the location and it's environment while using past knowledge to get by..

I think travelling is like ring-expierience to a boxer, only with expierience can you be sure in yourself and move with full confidence.
