There is one thing I never, ever will underestimate the value of: being able to visit my childhood home whenever I like. It is a farm house we rented until I was twelve (stay tuned for more shots of it). I love it so much to go there once in a while. Not only does it bring back memories, but it's a place of complete peacefulness.
It's just one of these places you can go to in whatever state of mind you are, and feel calm when you are there.
