I've been living in Gibraltar for three weeks now. With only two weeks notice, I packed everything up, said my goodbyes, and off I went.
Before that I dropped everything and travelled cross country for a new job in the south of England.
And for some people, it's just a way of life. Pack up and go somewhere new, find a new place to explore, take in the sights, the sounds, the culture.
I think a large part of this is that you tell yourself it's normal, no big deal. Downplay it in your head and go, to a place where you know no-one and can find nothing.
But that's only at the beginning.
After a little bit of time alone, exploring, you start to make friends. You become outgoing by necessity, you get out and move around and do things with the new people.
For me this is difficult. I wish I could say it gets easier, but for those first few weeks I don't think it does.
But the payoff is a new experience. To see a part of the world you haven't seen before. To live a different lifestyle, and taste one new thing in the cornucopia that life has to offer, if only you reach out and taste it.
Sure it can be difficult.
I've never felt that it's not worth it.
