If you're thinking of starting your own business

Here's an interesting career change story from Pittsburg. I think the writer was trying to extract some advice for career changers, but what I saw was a guy forced to make a career change who saw possibilities for a new business and who was fortunate enough to develop the skills and something that differentiated his way of creating video from the competition to become successful. It's worth the read and doing some thinking about what led to his success, especially if you're thinking about starting a business as your career change. What would differentiate you from everyone else out there who is doing the same thing?
