I watched a prog called How Did You Get to Be So Rich on Ch4 (yes I know)
Aisleyne HG is a really smart girl. Her dad was a Jehovah's Witness and she grew up in serious poverty. After coming third on BB she didn't buy handbags etc and knew the celeb rollercoaster would only last a short time, so she invested her first photoshoot in property in Kings Cross and learned about property investment. 'I didn't buy myself a single handbag or any treats' she says. Now ten years later she is a multi-millionaire.
I know she probably had a bit of luck along the way but I so admire her for her brains and determination. Good luck to her.
