"If you want to go fast, go alone; but if you want to go far, go together."
That was one piece of advice passed along at the just-concluded Democratic National Convention. The words were spoken by New Jersey Sen. Cory Booker, who said he was quoting "an African saying."
The proverb got a lot of retweets. And some criticism. One Twitter user, Christiana A. Mbakwe, said, "If someone starts an aphorism with 'there's an African saying' it's probably a mythical quote misattributed to a whole continent."
