Women notice details that most men don't. They notice if your belt and shoes match. They notice what kinds of foods you like to eat. They notice all the details, then make assumptions about every other area of your life based on these details.
I have also found that by making four simple assumptions in our lives we can immediately begin leading a more balanced, integrated, powerful life. They are simple–one for each part of our nature–but I promise you that if you do them consistently, you will find a new wellspring of strength and integrity to draw on when you need it most.
1) For the body–assume you've had a heart attack; now live accordingly.
2) For the mind–assume the half-life of your profession is two years; now prepare accordingly.
3) For the heart–assume everything you say about another, they can overhear; now speak accordingly.
4) For the spirit–assume you have a one-on-one visit with your Creator every quarter; now live accordingly.

The hardest thing in the world is to assume the mood of a warrior. It is of no use to be sad and complain and feel justified in doing so, believing that someone is always doing something it us. Nobody is doing anything to anybody, much less to a warrior.
We simply assume that the way we see things is the way they really are or the way they should be. And our attitudes and behaviors grow out of these assumptions.
