Since ancient times, people packed up their possessions and went looking for a new place to live and prosper. Stories about foreign countries where life is good play a big role in that choice. These stories colour the image people get of the place they dream about, unfortunately it often turns out to be an illusion.
But illusions and dreams are what you need: to change something, to give you a purpose. Imagination can also be an emergency exit.
And beyond that: what could be more wonderful than to be able to travel in your imagination, to be whoever you want to be?
