Well, probably their general principles! From http://highcallingblogs.com/7394/figuring-out-success-with-the-amish/#more-7394
Legacy. Who will want this after I’m gone?
Passing on values. How can this help me teach the important things to my children?
Home and family. How does this business bring us closer, rather than push us apart?
Giving back. How can I use this to help others, even those outside my immediate sphere of influence?
