If someone else stepped into your life for a week, would they do "you" better than you do "you"? Free from baggage and conditioned beliefs, how would they respond to your surroundings? Are there things in your life they'd be overjoyed for which you take for granted? Things they'd attend to easily which you'd been putting off for some reason or another?
Idk, just something I've been thinking about lately. Personally, I'm going to make a list of things in my life a stranger would be grateful for, things they'd do differently, things they'd take full advantage of...and see if I can't take on a similar attitude.
