Even if you know your ultimate goal, you may need a sign to direct you. If there was anyone who should be adept at seeing and reading the signs, you would think it would be Catherine Monson, CEO of Fastsigns International, the country's largest custom signs company.

But by Monson's own telling, it wasn't until her appearance on "Undercover Boss" this past Friday that the CEO of the $300 million-a-year company finally came to terms with the brutal truth of her own personal reality -- she's a workaholic whose devotion to professional success has had some big personal costs.
