Code 10/13 signals a positive and constructive mood. It also signals energy and the willingness to 'get on with things'. This is one of the mast positive of the mood codes. Negative moods can sometimes be picked up from facial expressions and behaviour. This is not so easy with positive moods unless they are exuberant and exaggerated. Code 10/13 signals in an unequivocal manner a mood that is well above the baseline. It is also above the more general code 10/2 (happy). With a mood as positive as 10/13 a person may not want to wait to be aked what his or her mood might be. So the person may wish to 'announce' this mood, without being asked: 'Today I am 10/13.' 'I feel 10/13 today.' There could even be a card which a person could put on his or her desk to announce to the world at large this 10/13 mood. Code 10/13 signals a positive and constructive mood. It is not a manic mood or pure euphoria. It is a practical mood.
