Whether you're commanding the international space station, pushing buttons, or making fire with sticks, party on.
Expeditionary Behaviour: "...the ability to work in a team productively and cheerfully in tough conditions" -Chris Hadfield.
The people who display these qualities are the people you would enjoy travelling with. They're relaxed, positive, and confident. They don't get on your nerves, and they contribute to the success of the team.
The psychological part is important too. Staying off each others nerves is tough enough in the regular world, and amplified in wilderness survival situations or out in space.
Stay positive. The world's a tough enough place without your friends and colleagues bringing you down.
A little humour can lighten the darkest situation and help the team overcome obstacles.
Fear isn't helpful. Physiologically, it impairs your circulation, judgment, and fine motor skills. It sets a bad example for the others.
If you're trying to figure out what to do in a situation, don't panic. Stay calm and work the problem. Don't lash out at people or tear down the team.
Misery and whining are never constructive. They make surviving dangerous situations far less likely. Instead, those attitudes spread and the team suffers.
Maintaining a 'Party-on' attitude keeps spirits up and leads to the best team results.
"Things work out best for those who make the best of the way things work out."-John Wooden
Nobody wants to travel with a miserable whiner. Party on.
