When I was little, my mother sold flowers at Camden Market in London, She couldn't leave me at home on my own, so I had to go to the market with her. As I grew older, I began to give my mom a hand and I really enjoyed it.

Things changed when I was 14. My grandma gave me a book for Christmas, which was all about making candles . I loved it so much that I spent all my free time making candles of all shapes and sizes. I made hundreds of them.

One day, my mother was ill so I had to go to the market on my own. I decided to take some candles with me and see if I could sell them. To my surprise, they were sold out in 20 minutes! The next week, my mom gave me some money to buy some wax (蜡) to make more candles. They sold out really quickly, too.

Nine months later, we decided to stop selling flowers. My mom and I couldn't make enough candles during the week, so some of my school friends started to help us. I paid them one pound for every candle, and we used to sell them for three or four times that. It was fun. and my friends worked with me in the market.

When I was 22, my uncle lent me some money and I opened my first shop on Portobello Road. Since then, I've never looked back, even in difficult times. At the first store, we only sold candles, but now we sell everything from designing furniture to paintings.
