Karen was a CFO for a small company who didn't actively manage her investments - she had a financial adviser for that.
Sometime in the year 2000, her friend got her to go to a seminar on investing and she decided to take a 1.5 year $22K specialized investment course. I would never take such a course as I would immediately be wary of a scam with pricing like that.
After that, in 2002, she opens her own account with $10K and begins trading.
In 2007, a "light bulb" in her head goes on and she takes a leap of faith to move on to attempting to trade full time for a living and leaves her job as CFO. She starts her initial account with her liquid life savings at $100K that she got from her former financial adviser.
In 2008, she had a 50% return, and some of her friends gave her money to manage/invest.
Fast forward to 2011, and Karen has made $41 million in profits!!
The video is an interview of her telling her story. I wholeheartedly agree with her work ethic about needing to diligently put time in studying and analyzing mistakes for improvement to reach higher levels.
By the way, regardless of her great success, I do NOT recommend anyone spending $22K for an investment course. That is waaaaaay too much- I don't care how good they claim their training is. With some searching, I think all the info you need is freely available via the library and other sources.
