Perhaps you’ve heard the story of the woman who, in preparation for cooking a roast, cuts off both ends. Her friend asks why she does this and the woman replies that it was the way she had been taught to prepare the meat. This sets off a snowball effect of daughters asking mothers why the ends must be cut off the roast. At last, the originator answers that her pot was too small to contain the large piece of meat.
I have come to see that each of us, in our own ways, have sets of values and beliefs that are based on the traditions of our families, the people with whom we associate, the books we read, even the region in which we were raised. All these factors account for our personalities, principles, and process of thought. These things make up our boxes.
