Holy smokes! The 5 year old me in Africa couldnt speak any English and my African may not be up to scratch any more!How am I going to talk to him?
Africa is a huge continent and the second most populous even...unless it's your actual intention to hide any identifying facts about yourself, I don't quite understand how you can suggest that 'African' is the language of Africa
I think that when you go back in time to advise your five year old self, it might be a good idea to tell him never to forget or forsake his humble origins and to be proud of them.
For me, I'd go back in time to imbue myself with a lot more self confidence, to believe in myself and to not put others before me or allow them to put/pull me down so easily - I was far too receptive to criticism as a kid, taking it all too seriously, not understanding that often people are so critical purely because they are envious and don't want you to excel.
