Donald, who describes himself as black, Indian, and Dominican, went to two high schools in San Francisco and Los Angeles. He liked the first school. It was challenging and the teachers were concerned about his welfare. But because of family problems, he left San Francisco and moved in with a foster family in Los Angeles. There he went to a school he describes as a "bad, bad school." He didn't learn anything and soon quit.
