This week, Tavi, now 15, launched her own online magazine, Rookie. Tavi is editor-in-chief of the title, and oversees a staff of around 40, who are, unsurprisingly, mainly much older than her.
The mag publishes fresh content three times a day, and is run around Tavi's school schedule, with stories being uploaded after school, at dinner time and late in the evening.
Tavi lives in Chicago with her family and is managed by her father, Steve. In her first editor's letter, she sets out Rookie's manifesto, and insists it is not all about 'how to be a teen':
"I don't have the answers. Rookie is not your guide to being a teen... It is, quite simply, a bunch of writing and art we like and believe in... Rookie is the place to make the best of the beautiful pain and cringe-worthy awkwardness of being an adolescent girl."
Hmmm. What do you think? Great entrepreneurial spirit, or a tad precocious? Would you encourage your children to do something like this?
