I really enjoyed this story (registration required) about Robert Serros and his Orlando-based company, Amber Diagnostics, in today's New York Times. It captures that magical moment for an entrepreneur when he realizes that his plan might just actually work out:
...in 1997, he made $1 million in revenue.
Even so, he still doubted his good fortune would continue and, just in case, he tried his hand at fixing and reselling old cars and even looked into real estate. "That's when my wife kind of dragged me by the ears and said: 'Stop coming down on yourself. You've got a good business going here,' ' he said. "And that's when it hit me - Amber Diagnostics is a real business."
