As a child, I had recurrent dreams. Dreams of the scarcity of water as being one of the main source of all tribulations here on our planet... In the time period I was dreaming this, it was hardly a consideration.
I envisioned a very dry desolate place. Almost like Dune, although I had never heard of Dune till many many years later. It wasn't exactly like that, but it became a main focal point in my life.
As a result, viable water sources are one of the most important consideration of my life journey.
