Reflection on the Flash learning

It is kind of frustrated to learn the Flash. I have spent more than ten hours on watching the Map tutorial, hoping to learn how to copy the techniques used in it so that I could apply those techniques to work on the final project. However, there are problems rising up frequently. It doesn't seem as easy as what I first expected. There are several reasons why I can't finish the entire practice and make a copy of my own. First, a whole range of operations involved in working out one task need lot of practice and memorization. Second, the concepts of layers and formats (visual types) take me many hours to understand them. Third, it takes me hours to understand that the first frame of the movie should leave out images. Fourth, the action scripts are different in different versions of the Flash. The one I use at home is Flash Professional 8 while the version in the tutorial is Flash MX. I realize that I need to spend more time to understand more about Flash and use it as a tool to create movie. No short cut in true learning.
