I heard Dean Sherman say this in his teaching on "Love, Sex and Relationships" there is a book too - a must read if you ask me.
Like he said, every problem relates to something wrong in a relationship somewhere. That I think too much of myself first or too highly about myself, I deserve this or that. Not loving my neighbour as I love myself, but putting myself first!
So,
Problems in my marriage, then someone(s) is thinking more highly of themselves than they ought to.
Problems with my kids, then someone(s) is thinking more highly of themselves than they ought to.
Problems at my work, then someone(s) is thinking more highly of themselves than they ought to.
Problems in my church, then someone(s) is thinking more highly of themselves than they ought to.
Problems in my city, then someone(s) is thinking more highly of themselves than they ought to.
Problems in my country, then someone(s) is thinking more highly of themselves than they ought to.
Problems in my world, then someone(s) is thinking more highly of themselves than they ought to.

Is this too easy? well yes! That's what's so frustrating about it. If I just start loving others as myself. treating people the way I would like them to treat me - what a difference. Think if everyone did that - wow!
But that is not the way life is - why not?
