If you want to discover new land then you must leave the safety of the land you are currently in. There is no other way, so you better get up and get moving if you want to discover a new area, a new ocean, or a new country.

It is possible to travel using Google Earth, but it is very different than actually visiting a country and being there. So, you need to leave something behind to discover something new. And while the old comes with safety, the new and unknown comes with insecurity, danger, fear, and who knows what... and yes, that is exactly what makes it so interesting, dangerous, and risky! But, once again, if you want to reach a new shore, you need to leave the old one. Are you ready to do that? Are you willing to do that?
