I really liked this article and I know it's true because I've seen it happen to me.
I actually wrote an article about 6 months ago that adds one more layer to this here: How to Change the People Around You
Basically, I just point out that when you do this process of changing yourself, the people around you might not necessarily change immediately. Meaning, if you become a tidy person on Monday and you get home on Tuesday, it doesn't mean your partner will all of a sudden be interested in being Tidy. Or if you start exercising tomorrow, it doesn't they will too. Sometimes it takes a while for people to "catch up". I believe it has to do with your own re-alignment on the inside which takes a while.
