Work at school and Uni, to get an education - you will always have it. Travel - do it cheaply if you have to, but go. There's no rush to marry anyone. Save money if you can. Don't smoke, and limit your drinking. Be nice, but don't take any shit. Keep in touch with your family and friends. Listen to advice, but try to make your own decisions. Life can end up being a series of missed opportunities, if you let it - so pay attention.
