The difference between purpose and mission

Purpose is not just for big corporations. Nick talks about harnessing the power of purpose at his two pizza restaurants in his Ted talk below.

He has a great explanation on the difference of "Purpose" and "Mission and Vision" (around the 2:40 mark):

He goes on to explain what values are:

Our values are how we do what we do.
