The grass is always greener on the other side of the fence.
I live in New Zealand, considered by some as a great place to live.
But when you live in a country you can forget about the things that make it special.
To me people who live in Europe have more places to visit, history, customs, personalities and diverse scenery.
The things I do not get living here seem to become the things I envy the most from people living elsewhere.
Reality I have found is that its the people you share your time with become more important that the location you spend your time.
I guess that is why holidays and travel allow people to experience other things and remind them at times what they have where they live already.
