Sometimes what we seek to gain through "winning" a conflict is not worth what we're refusing to sacrifice. And true compromise often involves sacrifice: As on the path between Scylla and Charybdis, the monsters of Greek mythology who lie on either side of a narrow strait to devour sailors and ships, either way you go there will be losses. Through life experience we gradually learn to differentiate between the ideals, values and principles which can, and those which cannot, be compromised.
