This insight is key.

I've had challenges in my life. At no time have I ever lived somewhere for more than two weeks with no running water, because I was born American and sufficiently affluent and lucky to be both in towns with municipal water and in buildings connected to that water. So I get to completely cross off "Has clean running water all the time" from my list of needs and wants, and not everyone does.

... and I gotta say, potential employers like you a lot better when you've had a shower that morning.
