Calvin Coolege said it best...

Genealogy's Star blog posted this, "Paraphrasing, the world is full of intelligent, educated, talented genealogists who are not great. Greatness in genealogy does not come as a result of either money, fame, education or talent. It comes from persistence and observation of detail."

In other words, "Persistence pays off."
