     He has vowed that he will not stop building his business until it is worth £100 million. But hard-working

Owens can stop for at least a moment's celebration after making his first £1 million at the age of 16. Owens,

who has used a computer since the age of seven, began teaching himself basic web design at the age of ten

when he was given his first Mac computer. He used his pocket money to fund his first business project,

website Mac Box Bundle at just 14 which has made £700,000 since its establishment in 2008. Mac Box

Bundle sells a combination of popular Mac applications which are worth up to $400 together for under just

$100 and donates 10 percent of the money to charities.

    He then established an advertising company Branchr a year later and worked on the business after school

and at weekends. Branchr made a surprising £500,000 in its first year. Branchr works as a platform for

website owners to sell advertising.

     Owens, from Northampton, currently employs eight staff-all adults-around the UK and America as sales

and technical assistants. The young man lives with his parents. His mother who is a company secretary said

he was inspired to go into business after observing the huge success achieved by Apple's chief executive

officers (首席执行官) Steve Jobs.

     Owens said,"I think everyone has business sense in them, and they just need to gain experience and be

determined to make it. There is no magical formula (法则) for business, It takes hard work, determination

and the drive to do something great. My aim is to become a leading name in the world of Internet and mobile

advertising and push myself right to the top of the game.

     The teenager insists his professional success has not affected his personal life, and says his interests
