Well, now is the time for Prince Harry to prove himself.
He has distanced himself from royal duties, if not royal finance, and the world is his oyster. He is in an enterprising country which I imagine offers a good outdoor life, which again I imagine is where his talents lie. A polo pony stud, outward bound experiences, military training, explorer type activities, training/opportunities for the disabled, working for an established charity? Many, many opportunities.
He has youth, health, wealth and contacts; now he has the opportunities to utilise them and prove what sort of person he really is.
