Travelling relates to the word moving or on the move. Everyone's definition of travelling is different depending on the context in which it's used. As in - I absolutely hate travelling to work every day, it SUCK! - or - we're off travelling around the world WIPEE! -
To me though, travelling defines soaking up new places and experiences, enjoying life as much as possible and opening up the mind to a new way of thinking.
Give me a laptop, an internet connection a glorious income on-line and my wife and I would be travelling all the time - living LIFE :)
