Don't settle for the kind of narrow, sketchy map most people have at about mid-adolescence, when they stop revising. As if this isn't already difficult, reality itself tends to change as time goes on. Reasonable assumptions about the world from the 1960s are no longer useful in the year 2000. Further, assumptions appropriate to youth won't work in adulthood. Map revision is admittedly painful.
Truth is more important than comfort.
Don't automatically reject someone challenging you on something. Realize and accept your own imperfection and weaknesses. Learn to be comfortable with the idea that you might be wrong about some things. It makes it easier to accept the imperfections of others. Jesus made it a point to accept the service of imperfect people, because there aren't any other kind.
