I have loved to travel my whole life and felt trapped in my home country. When my travels was most extreme I traveled to a new country every 3 weeks. After a while I got tired of not having enough time to learn about a place before it was time to leave again.
Also I had dreamed for as long as I could remember to move abroad, so I did it. First place was Milano, totally random and just because I could find a place to stay there really fast.
I bought a one-way-ticket and wanted to stay for a minimum of some weeks, which very fast became 5 months and one of my best experiences ever!
Now I travel around and stay for 3-6 months in every country.
