Defining Core Values can be challenging for individuals and companies alike. We think of Core Values as the 5-12 things in life that are truly worth living for, and if violated, we feel compelled to do something about it. We are each made up of roughly 50-100 different values. One exercise you can do to discover your values is called Mountains and Valleys (proposed by the folks at CultureSync - check them out for other free tools: http://www.culturesync.net/toolbox-old-2/) . For more information, we highly recommend reading Delivering Happiness by Tony Hsieh and Tribal Leadership by Dave Logan, John King, and Halee Fischer-Wright. Both books have heavily influenced PermaHub and would give you insights into our philosophies.
