One of the biggest benefits of traveling abroad is being able to return home and get a fresh perspective on where you live.
French engineer Geoffroy de Reynal had a powerful awakening after leaving his home for a year and coming back.
"I was living abroad in Montenegro for a year, and there are not much people living outside there," he told ABC News. "When I came back to France, I was surprised by the number of homeless in the streets, so I decided to come up with an idea to help them."
France has seen an increase in homeless over the past decade due to the global financial crisis as well as an influx of migrants from Africa and the Middle East. According to France's National Institute of Statistics and Economic Studies (INSEE), more than 12,000 people sleep on the streets of France.
