His Wiki entry makes no bones about his Republican/conservative views, that he wove those values into his motivational works.
Tragedy was no stranger to this gentleman:
In 1931, when Ziglar was five years old, his father took a management position at a Mississippi farm, and his family moved to Yazoo City, Mississippi, where he spent most of his early childhood. The next year, his father died of a stroke, and his younger sister died two days later.
I also recall hearing of his incredible Christian faith as he walked down the aisle to view the casket of his deceased daughter. Wiki says she died in 1995 so she could not have been that old (his YOB 1926)
Neither was failure - in the early years - and poor health at times. All added to the richness of his messages.
