Q: Kinshasa, DRC (CNN) -- Kinshasa hasn't had an easy time of it. A decade ago, the capital of the Democratic Republic of Congo was a broken city, ravaged by years of war and infighting. Of late, however, Kinshasa has witnessed a resurgence, with many expatriated Congolese returning to build a new city.

"When I came back, people thought I was crazy. "[They would ask], 'why would you go into a country where there is war? Where nothing is working? Why not stay in the States and make your life?'" says Joss Ilunga Dijimba, who returned to Kinshasa in 1996 after studying in America. Today, Dijimba runs his own eponymous business, manufacturing plastic bottles for the pharmaceutical industry.

"In the USA, everything has been done -- everything. In Congo, there is still a way to make things right. I am a Congolese. If I'm not going to make it, who's going to?"

In agreement is Olivier Ndombasi, who always planned on building his fortune in his homeland. Like his elder brothers, he studied abroad in the hope of bringing back knowledge that could improve the family business: groceries. His father's small store has now turned into a supermarket franchise called Peloustore, with four locations and more on the way.

"It's very exciting to be able to do things in a new environment, and do things you didn't think you'd be able to do," says Ndombasi.

"The challenge is great, but it's very exciting."

Many agree that there are obstacles, but returnees often cite the exhilaration of starting with a clean slate.

Q: One morning, Ann's neighbor Tracy found a lost dog wandering around the local elementary school. She asked Ann if she could keep an eye on the dog. Ann said that she could watch it only for the day. Tracy took photos of the dog and printed off 400 FOUND fliers , and put them in mailboxes. Meanwhile, Ann went to the dollar store and bought some pet supplies, warning her two sons not to fall in love with the dog. At the time, Ann's son Thomas was 10 years old, and Jack, who was recovering from a heart operation, was 21 years old. Four days later Ann was still looking after the dog, whom they had started to call Riley. When she arrived home from work, the dog threw itself against the screen door and barked madly at her. As soon as she opened the door, Riley dashed into the boys' room where Ann found Jack suffering from a heart attack. Riley ran over to Jack, but as soon as Ann bent over to help him the dog went silent. "If it hadn't come to get me, the doctor said Jack would have died," Ann reported to a local newspaper. At this point, no one had called to claim the dog, so Ann decided to keep it. The next morning Tracy got a call. A man named Peter recognized his lost dog and called the number on the flier. Tracy started crying, and told him, "That dog saved my friend's son." Peter drove to Ann's house to pick up his dog, and saw Thomas and Jack crying in the window. After a few moments Peter said, "Maybe Odie was supposed to find you, maybe you should keep it."

Q: Robinson Diaz lives in a small cottage high in the Andes Mountains of South America. Diaz is a "cable racer", and every morning he faces the difficult task of taking the local teacher to her school. To do this, he first walks for an hour up to a place the locals call Los Pinos, right at the edge of the 400-foot deep gorge of the Negro valley. Here, one end of a thick metal cable has been fixed to a wooden post. The cable stretches right across the deep valley to the other side, a kilometer away.

A metal hook is fixed to the cable, with leather straps hanging from it. Diaz fastens the straps around his shoulders and waist, does a quick safety check and then, without hesitating, throws himself off the edge of the mountain. Attached to the cable by only the metal hook, he rapidly picks up speed and soon he is racing through the air. Crossing the valley by wire takes him 30 seconds, instead of the two hours it would take him to walk down through the rain forest and climb up the steep muddy slopes on the other side.

As Diaz begins his trip, Diana Rios, a 23-year-old elementary teacher, is waiting on the other side of the gorge for the moment when he will come racing through the mist towards her at 100 mph. She will then return with him, hanging on to him as he goes back along the cable. Diana had no idea when she took the teaching job that just getting to work in the village school would be dangerous. "At first I wanted to cry," she says, clutching her hook as the metal cable starts to rattle violently at Diaz's approach. "But I soon got used to it." She still prefers to go with Diaz, though, rather than making the frightening and dangerous crossing on her own.

For the inhabitants of Los Pinos, the wire cable is a lifeline. For more than 50 years, it has served the community as a form of transport to and from the rest of the world. Everything that comes arrives via the cable----bricks and wood for building, sacks of rice and corn. Pregnant mothers, who must get to the nearest clinic, cross the wire during the darkness of the night, returning with their newborn babies. It is dangerous, but they have no choice.

This time Robinson Diaz makes a perfect landing on Diana's side of the gorge. For him, the dangers of this daily journey are insignificant. "What I'm really scared of are snakes," he says. "This is nothing in comparison." Then Dianna straps herself into her harness and hooks herself up to the wire behind Diaz, holding on to him tightly. He turns, flashes her a smile, releases the brake and kicks away. Within seconds, the teacher and the cable-racer have disappeared back into the mist.
