I think that English is "slawesome."

As you watch the video, make note of the ways you notice Ernest Shackleton demonstrating leadership.  

 He shut down the engines to preserve fuel - a poor decision, I guess, but leadership. 

They must winter in the pack and sail on - again, his decision. 

Everyone was equal and busy all the time as far as tasks go - nice living quarters, etc.

 "Strength lies in unity." - Shackleton

He looked to the future and didn't dwell on what had happened in the past. 

He decided when to leave - a judgment call, apparently - how does one determine such a thing?

With his deciding to go on the journey himself and probably sacrifice himself, he earns respect and such things, electing action over possible self-preservation.

What concepts (qualities) of leadership do you notice?

 Honesty present in his ad of "questionable return" was key and important before setting out.

 Fair division of labor was key. 

Camaraderie.

 Optimism.

What might these concepts (qualities) look like for you in your classroom? With your colleagues?

 Remaining optimistic throughout the trials and travails of educating students of all varieties can be a tough thing to do (albeit not as tough as walking across Antarctica on foot and stuff like that), but it's something we must do, as certain students will remember those times that we flag, aren't on the top of our game, etc. 

Promoting community through camaraderie through shared support, equality, etc. 

Choose a concept (could be a strength or a challenge) and create a visual reminder of it - something that you could post or use as a motivator for yourself - SHARE.

A tiny lifeboat that's all rigged up and stuff - outlasting hurricanes and such things.
