Okay, I've watched this film a couple of time but didn't really get what 'rocky' was talking about till i watch this part again on youtube. Kinda true.
We all have our demon and 'rocky' (stalone) speak through real-life experience.
It ain't life if it ain't hard. Life may knock u down, but they will never knock you out!
