Comp 4

I am struggling to come up with an idea for my composition 4. The idea I have came up with is how moving has forced me to have an outgoing personality to overcome the diversity I have faced being a "new kid". With the personality I have gained it has helped me make friends and feel welcome where ever i have moved but it was hard in the beginning but I finally stuck it out and made many friends. If I didn't I would have lived a miserable life I believe. The problem with this is I have moved so many times that I don't know how to fit all of the events in. What do you guys think I should do? is this a good idea to build on or not? How could I put all the events in my memoir or should I shorten it down?
