You had to be proficient in at least one sport, the more dangerous and expensive the better.
Languages were an asset- for blandishments if nothing else- and smarts: not bookishness so much as worldliness.
It wasn't necessary to be drop-dead handsome but you had to be charming, and you got extra points for a reputation for danger and good times.

Connections were essential, whether acquired through school or sports or socializing or business, if you were the sort who went in for business.
