Well, I think it can work both ways: it can be good, widen your comfort zone, or a way of escape.. (or a scary experience) or both/all of that lol!
Someone on this forum said that travelling was a really good experience, meeting friendly people etc. He lives in Brasil with love of his life I think?
I also have a friend who traveled and moved a lot, married a guy in the US (he's American) and then they both came back into her home town, so hm? (She just went for a vacation with relatives first, then stayed at a hostel and met him there..)
Another friend met her man on a summer vacation too..
I wish I traveled more when I was younger, but I saw it as a way of escape then too.. (It's cheaper to travel when you're younger

)
You can also meet interesting new people..
I think it's best to read some books on communication and/or take some courses in that, and then go with a friend somewhere not too far away and see if you like travelling.. (It's easier for me to go with a friend or two, even if we split up then there...) And how to go through an airport etc. if you haven't gone already (I'd probably be scared to go alone the 1st time lol)
See what destinations are cheaper to go to (both travel and living costs) and you can do interesting things there for free or cheap... (I loved London cause almost all the museums and galleries were free, with free tours too.. and you can meet and talk to people there.. not sure if it's still the same, double-check any destination before you go.. staying in London can be quite expensive though, so you might wanna check cheaper destinations.. and then see what you can do there too..)
a 'dip in the water' may be best, before you decide something big like that... (like a short vacation) to see if you even really like it there, maybe meet some people..
Then you could try to look for work or study there... or at least ask around how to go about this...
I really liked going to the capitol and studying there, it mostly did feel like 'a clean slate'... So I recommend something like this - you can do it in your own country or elsewhere, depending on your funds $$$ and other resources..
Some of my friends from Uni/dorm stayed in the capitol (it's also easier to get a good job there), some also studied abroad... Mostly they had good experiences and 'widened their horizons'...
