Motivational Speaker Zig Ziglar Dead at 86

Credited with helping develop the self-help presentation industry

Zig Ziglar delivered his message of positive personal transformation for business success to millions of people and helped create the profession of "motivational speaker."

A traffic signal, to Mr. Ziglar, was a "go light," the morning alarm was an "opportunity clock" and every setback could be a steppingstone.

Mr. Ziglar, who died Wednesday at age 86, preached in the tradition of American self-help that stretched back through Dale Carnegie and Norman Vincent Peale.
