Rocky's Character

So, as we're progressing through Rocky we get to the scene were Apollo Creed asks Rocky to fight him in the bicentennial fight. You would think Rocky would jump on this opportunity to prove that he has at least what it takes to take on Apollo maybe not defeat him, but give him a good fight. However, Rocky declines almost immediately because after so many people calling him worthless he believes it. He believes that he isn't good enough to fight Apollo, just to spar with him. However, even though Rocky seems to think that he is worthless, he always goes out of his way to help people such as the girl that was hanging out with the guys on the street. It will be very interesting to see where Rocky's character goes by the end of the movie.
