Reasons for travelling
Travelling is a life altering experience and (usually) a 'once in a lifetime' experience! No matter how broke you return home you will have memories, friends and experiences that no one can take away from you.
And that is exactly why people set off on trips around the world. They are after a life altering experience. They want to see new things, meet new people, learn about different cultures, explore the world in their own pace and actually experience what others only dream about their whole lives. Sure, it requires serious saving and planning. Sure, there will be people around you who don't understand or want you to go. Whatever it is, if we are determined, nothing should stop us.
These are some of the purposes of travelling. What about you? What is your main reason for travel?
