Excellent points. I would only add my suggestion that these are questions that every character, not just new characters, should constantly evaluate and re-evaluate since they may change over time during the course of RP. A brand new character might not have answers yet to all of these questions (and might not want to have all of them answered right out of the starting gate), but may develop them later. I can say from experience that things like "greatest love" and "greatest regret" often mean more when they are developed organically through the course of RP with your fellow players.
