Born on 18 December

The 18th blends authority with humanitarian breadth: a 9 that knows how to run things. These people do their best work when personal ambition and public benefit point the same direction, and feel strangely hollow whenever they split.

Nine arrives with something already accumulated: an intuitive grasp of the whole human range, as if the other eight numbers had been studied in advance. It contains every digit (add 9 to any number and it reduces back to that number), and the life tends to be correspondingly wide.
