The Rev. Demond Wilson, who played Redd Foxx's son on the 1970s television show "Sanford and Son," says people can be whatever they make themselves. "Success and failure begins with you," he told students at Carroll High School in Monroe, La., this week. But Wilson warned the students, most of whom were black, that they must do more and work harder to get where they want because of prejudice. "Black kids have to be twice as ambitious, twice as motivated, and have twice the goods to compete," said Wilson, who also starred in a black series of "The Odd Couple" and in ABC's "Baby, I'm Back" with Diahann Carroll. The Monroe school system's drug-free schools program paid for his speaking engagement.
