In the late 1700s, Captain James Cook made history by being the first European to discover Hawaii, circumnavigating the globe in the process.

Captain Cook learned that sauerkraut juice was effective in preventing scurvy, but tasted terrible.
His tactic for getting his crew to regularly consume the awful stuff is a remarkable example of shrewd psychological insight translated into effective leadership.
Take a minute for some sauerkraut leadership.
