About the getting to "involved with exterior helping". I am really all for learning it the hard way, so that even if im on a shipwreck and end up on a lonely island i can induce at will. But since we live in the times we live in and more and more helping accessories is presented i see no problem testing them, and if i do find a thing that works great for me i would stick to it. The goal is to have LD. And with more practice and experience being inside the dream and testing, learning and so on i believe it will be even easier if you decide to put the helping aid away. Then you got so much experience being inside a LD that you will recognize by yourself.
