Basic plotline: cuckoo in the nest pubescent boy who seems to always have bad days while the rest of his family have perfect ones, wishes his family they could experience a little of what happens to him. And they do... big time! Cue silly moments involving a disastrous driving exam, a drunk Peter Pan & a green marker pen that may to may not be poisonous... It's fun.
The lesson of this film is a very, very simple one: we can all have bad days but it is what you do with them that matters. All (well, almost all perhaps) bad days can be turned into good ones by a combination of grit, team work & loyalty, and a sense of abandon (in for a penny... etc) And the magical "when it's over, it's over... but not until then".
Leaders (and in the case of this film, there are three) have a critical role to play in this creating the environment in which such learning (or what to do with bad days) can occur. Leaders must show their capacity to do this and praise others for doing it too. Leaders also have the responsibility to make it OK for people to make mistakes and have a bad day, sometimes. It is a critical!
When was the last bad day that you had... what did you do with it? And what/who helped you to do that?
