Overall,,,
We appreciate the fact that you're trying to give a message with worthwhile content (i.e. follow yoru dreams).
But... I didn't quite see a strong enough link between sk8ing, hateful anti-flash comments, and following your dreams (referring to the final message here). But then again, it could be just me.
I understand how you feel about all your haters, but still, I don't think that you should make a flash just to degrade them; it's putting you down to their level, of which you probably aren't. Just press the "Flag this review as abusive" button and let the newgrounds bots take care of the rest! :D
But overall, I'm sure that like many people out there, you have potential of some sort (and yes, I agree with your overall message) - so keep going, and good luck with any further flashes!
