HUEHUETENANGO, GUATEMALA—Carmen Harroyo spends 16 hours a day picking coffee beans, but the weather-beaten 17-year-old said Monday that she is glad to do it if it helps give a single coffee drinker a much-needed morning boost. "I make $2 a day and share a room with my five sisters, but all the hard work is worth it if I help just one American suburbanite jumpstart her day," Harroyo said, batting away a swarm of mosquitoes. "I appreciate the opportunity to touch another person's life." Harroyo said she dreams of someday helping people get their antioxidants by picking sticks from bushels of green tea until her fingers bleed.
