A TEENAGE BUSINESSMAN
When most 14-year-old boys are playing football or computer games after school, James Kenyon from Manchester is running his own successful business. “I’ve heard of a company in Scotland selling homemade bath products and thought it was a good idea.
My dad said I could do that, so I decided to take a chance,” James explains. That was two and a half years ago.
James started selling bath products to his friends and neighbours, but soon he began working for two local shopkeepers. Since he started his own soap company, selling homemade soap, bath salt and other bath products, James has earned over & 4,500.
James is proud of his success in business but he thinks there are more important things in his life. “I’ve learnt lots and I’m really enjoying it, but my school work always comes first.
James` s parents are proud of their son, they think that he plans everything really well – he does homework and he can focus on the business in his spare time. James says his parents have been a big support.
In 2006 James became a finalist in the Enterprising Young Brit Award. James is just one of an extraordinary group of enterprising young British businessmen who have innovative ideas and enthusiasm for business. Age and experience is certainly no obstacle to their success; their ambition and energy inspires them to create their money-making ideas.
