(Inc) — Keep to Your Principles: Fred Keller, founder and CEO of West Michigan plastics manufacturer Cascade Engineering, keeps a card in his pocket with a set of reminders from John Wesley, 18th century Methodist theologian, on conducting a good life. Keller, who is an active Methodist, says his religious practice grounds his business activities. “It’s a matter of being grounded in principles and carrying them out,” Keller says.
