The more willing you are to travel at a moment's notice, the more opportunities you can access. Day jobs will limit travel, so will mortgages and car payments.

Being available and flexible has made a monumental difference to my career. 

Long-haul flights are brutal to your body, and jet-lag can cripple your productivity while you acclimate to your surroundings.
