Here's a short story:

What can technology do to make the world better? Three young people are starting new businesses to answer the question. Eighteen-year-old Mach was the youngest person in Poland to receive money from others to develop his company. He started FIVE, a mobile messaging app , for deaf people. The app lets deaf people create their own hand signs to communicate with friends. The app now has more than 10,000 deaf users. And Mach thinks there will be about 150,000 more deaf users next year. Mach says, "I love to create. I will stick to it to the end of my life." William Zhou was born in Beijing and grew up in Canada. He strongly wanted to make a change in education. So he created CHALK. It is a group of programs that supports individual teaching and learning. CHALK is now used in 20,000 schools by more than 100,000 users worldwide. Zhou says you have to find something you truly care about. Or you may just end up giving it up. George was born in Tanzania . He learned about renewable energy in Europe and began thinking about using solar energy in Africa. Tanzania is a place with bright sunshine, but more than 90 percent of people have no electricity to use. After graduation, George returned to Tanzania and started his own company, SunSweet Solar. It has found early success in rural areas. George hopes to create jobs and help build his country. He understands the process will take time. "But I think we are on the right way." (End of story)
