Theres no one place that can open your way of thinking, but i think that travel in general, especially on a world scale will definately open your mind. When you experience the life of another culture, and if you enjoy it, and embrace it, whether you choose to or not, you will grow as a person.

Europe is a wonderful place, if for no other reason than the fact you can simply board a train and make a day  out of going to another country and back home again. You can go to Germany and then train to Switzerland, or Italy, or France etc. Then go see the Alps, its all right there. Couple that with the history thats visible and palpable in Eurpoe.

Imagine further, Africa.  The culture there is still primarily intact. The  vegetation unchanged. The animals more exotic and beatiful than that of any other place.  The people  are far kinder than the media would have you believe.

Some people make pilgrimages to the places they have roots, Ireland, England, Scotland, Norway, china etc. I think these are deep and meanful trips to many, much akin to a spiritual pilgrimage
