I think so because it Seems to me that there is a great diversity of in landscapes and different ways of live lifestyles to choose from.

I would like will be great to live in NYC for one or two years and then before moving to somewhere in California for another two years or something like that. After living this amazing experience I would like to come go back to my homeland.
