I work fulltime for a outsourcing company that really doesn't care about my location, just the delivery of working code.
Although after 5 years of nomading I also have this feeling of creating roots, I've managed to do that going mostly to the same places every year for 2-4 months.
Lifestyle. Moving around constantly was great in my youth, but thinking ahead I realized it would be in my long term best interest (social and psychological) to grow roots and settle down somewhere. That said, moving around a lot got me the exposure and experience to know WHERE to land.
I'm glad I did it in my youth, but that's a window that's closed. I'm happy where I landed and look forward to a comfortable yet challenging life.
