Mallyveen Teah, 53, has been homeless or couch surfing on and off for the past 25 years. Now, he walks from his job at a construction site in Arlington, Va., to his new home, a one-bedroom apartment.
"Something as simple as giving a person a set of keys to their own place makes a huge difference in terms of their outlook on life, the world," he says.
Teah is part of a campaign launched by a nonprofit group in New York four years ago to permanently house 100,000 homeless people.
