Questions: What was young Barack's ambition when growing up?

Answer: to become Prime Minister of Indonesia.

This comes from a New York Times Magazine article by reporter Janny Scott who describes a conversation from Pres. Obama's youth in Indonesia:

“What do you want to be when you grow up?” [Obama's stepfather] Lolo asked Barry one evening, according to Saman [Lolo's houseboy].

“Oh, prime minister,” Barry answered.
