Travel has interesting ways to question your opinions. The preconceptions your mind conjured about a city, a country or a skin colour based on an overdose of movies, songs and alien-sounding names were never there. It was just your need to simplify and classify everything into boxes. So you dig further and question opinions which are central to your being. Those questions slowly change you and alters you in an inexplicable manner.
Travel isn't great because it's a getaway. Travel is great because it changes you, one small piece at a time. And initially, the progression is so subtle that you come out unscathed from the evolution. No disheveled credos and no ground slipping from your feet. Your opinions just become a little jaded with life experiences. Travel opens you up without you even knowing it. It makes you try more and gather more.
But this subtlety remains only till the time you don't know what it does to you. Once you do, it's effects are exponentially addictive and you will never get enough of it. You will keep popping a 'traviagra' until you become something of everything. A gender/colour/border/creed traversing mutated creature whose tribe is thankfully growing. Every conversation, every smile shared with a stranger, every discovery then is within and without.
