Dogsledding and PURPOSE: What’s the connection?

What can DOGSLEDDING teach us about our purpose? The dogs attached to the sleds seem to know their purpose and there is no stopping them. After a good breakfast, they are raring to move and pull the sleds through the snow and into the woods. They were simply meant to do this. I wonder if the excitement they have is because they know what their purpose/WHY is? There is a relationship between knowing your purpose and the motivation and energy that follows. What a neat example to be around these dogs and the enthusiasm they demonstrate….all stemming from knowing their purpose.
