Stumbling on the Small Things

So today I am starting my first training for a professional coding.  It is nothing great or even something super advanced. But I am really excited that I am learning the basics of AS3.  I have gotten pretty good at AS2 and for some reason every time I have tried to pick up AS3 I have had issues. It might be the fact that I might have missed some small thing back when I should have learned code or it could be that the Code is so close but so radically different in the more basic of elements.  I am truly excited to move on considering I have learned about many of the new features that this language has.  So wish me luck on my first training. I hope I am not too bored.
