I'm not quite sure if I am considered a seasoned hubber or not but just my few words of advice. Write about topics you know about. While a life story may attract some readers it will not usually attract enough to make you money (if that's what you're here for). I'm not saying that you shouldn't write about yourself (I do also), just not all the time. I read what you had published so far and I would suggest breaking down the second section into 2 or 3 sections to make it easier to read.
As for the rest, keep reading the learning center, write quality hubs, participate in the forums (If you're up for debates) or answers section and enjoy yourself.
Welcome to HP! Good Luck!
