you feel when you see people using your app? Luca: It gives me a strong sense of achievement. I feel like I'm making a difference. Reporter: That's wonderful! What advice would you give to other teenagers who want to learn programming? Luca: I would say, "Just start!" There are many resources online, and practice is the key. Reporter: Thank you, Luca! Now, Maya, why did you start collecting postcards? Maya: Well, I think postcards are a great way to learn about different places and their cultures. They're like little windows to the world. Reporter: That's a beautiful way to put it. What's your favourite postcard in your collection? Maya: My favourite postcard is the one that shows the Mogao Caves in Dunhuang and it's so beautiful. Now there are over one hundred postcards from thirty-two countries on my walls. Reporter: It sounds amazing. Do you have any plans to travel to these places? Maya: Yes, I do! I hope to visit all these places one day. Reporter: That's a great dream! Thank you both for sharing your hobbies with us. Luca & Maya: You're welcome!
