Travel is what will change you and the world for the better.
My passport is filled with stamps from all corners of the world - Romania, Algeria, Peru, Cambodia, Tibet, Iran, Turkey, Estonia, Russia, and so many more amazing places - and they've all had an amazing affect on me.
The most important thing we can do is to open ourselves to other cultures. Encouraging eachother to travel & explore can only make us better people.
Put your mind to it. Make it your goal. Cross a border and change your life.
