Rick Chollet was a financially successful entrepreneur until March 18, 1991. He had even been the president of Brookstone Company, a small mail order business that he transformed into a national retail leader selling products for craftsmen. But on March 18 Mr. Chollet locked the garage door of his New Hampshire house, climbed into his BMW, and turned on the engine. He left behind a note that read, “Please forgive me, but the thought of going through the torture of living is just too much to bear.”
