I voted "It's great!" and love all the points you made.

One possible suggestion--take out "My point in this discussions was these pessimists that you listed off to me, they don't have families do they? Pessimists push people away because they don't believe that their life is going to be successful, that they can't give the world anything, and they deserve to be alone. Optimism is the foundation of family because they believe in one another, love one another and are convinced their love with succeed through time. "

Though I agree with all the points made in this part--you speech might be easier to follow without this. Congratulations on your success!
