I always had that feeling and dude just go for it. When I was 17 I went to Australia, just had an open-ticket, a suitcase & a bit of money. All was decided in one week and the week after I went. Eventually spent 7 months there.
When I was 23 and graduated and did the same only went to Africa, got the idea and went 2/3 weeks later, ended up for almost a year there back then...
Always wanted to go back and from next month on I will live there...
