Ok, I think I can answer a few of your questions. The method you choose to start LDing really depends on you. Some people have found DEILD easiest, some have found MILD easiest. It is different for everyone. I would say that WILD is most reliable in the long run. If you can perfect WILD, you can have really nice LDs pretty much on demand. When you have a lucid dream, you are you. It is first person, you can feel, smell, hear, and taste. Being excited for having your first lucid isn't a problem, unless when you become lucid you are so excited you wake up. That can be frustrating. The easiest way to fly, I would say, is to genuinely believe that you can fly. And you can LD as much as is physically possible, there is nothing wrong with this. Good luck exploring the dream world.
