The important thing isn't the house. It's the ability to make it. You carry that in your brains and in your hands, wherever you go... It's one thing to carry your life wherever you go. Another thing to always go looking for it somewhere else.
People's dreams are made out of what they do all day. The same way a dog that runs after rabbits will dream of rabbits. It's what you do that makes your soul, not the other way around.
