Books: 'Nonprofit Management 101'

In the introduction to his new book, "Nonprofit Management 101," Darian Rodriguez Heyman, managing partner at the CODE Green Agency and former executive director of the Craigslist Foundation, shares a story about Bill Cosby.

Apparently, at one point while pursuing his master's degree, Cosby and his master- and doctorate-level classmates spent a frustrating afternoon debating the age-old quagmire, "Is the glass half full or half empty?" Afterward, he shared his frustration with his grandmother.
