#4 Savannah Britt, 17

Savannah Britt was a published poet by the age of eight. By nine, she was hired as a paid reviewer of children’s books for The Kitchen Table News – a New Jersey newspaper with a readership of 70,000. But when that newspaper went under, Savannah was left unemployed at the tender age of 11.

She bootstraps herself and started her own publication – a magazine called Girlpez – making her the youngest magazine publisher in the world. The magazine features coverage of events, like concerts and fashion shows, along with interviews from the likes of Shwayze, Kevin Rudolf, and Dawn from Dannity Kane.

#3 Philip Hartman, 17

Philip Hartman became an entrepreneur when he was eight-years-old. That’s when he started building slingshots that shot both BB’s and arrows.

When he was a home-schooled high school senior at the age of fifteen, Philip spent most of his time cultivating two somewhat more advanced entrepreneurial ventures. One was a new system for fusing optical fibers that is cheaper, more efficient, and more dependable – an invention for which Philip won the 2008 Young Inventor of the Year award.

The other was called Steam Viper. It was a device that emits steam onto a windshield and is capable of defrosting a frost-covered windshield in about 15 seconds.
