Great jeopardy exists when we think we have it all figured out, no matter what the subject. A sense of personal omniscience limits our options to the current level of our knowledge and experience. The only safeguard against this kind of jeopardy is to remain humble and teachable. Always keep the door open to more insight, even insight that might challenge your most deeply entrenched position. Refusing to open the door to outside input makes us defensive, unteachable, and a pain to be around.
