Eminence had some great ideas, but I wanted to add a little to them. When it comes to dreaming, sometimes you just have to get creative... well, you always have to be creative. I'll use the illustration of flying.

In one of my LDs I wanted to fly, but ever since a certain dream I had, it's always been difficult for me. So, I decided to try something new and just felt that if I jumped into the air I could imagine a great wind beneath me blowing me upward. It was starting to work beautifully... but then I woke up. My point is that there's never just one way to do things in dreams. Use your imagination!

As for trying to go to places, going through doors is just one way. People also use mirrors or spinning to get where they want to go. In regards to spinning, the way I would go about it would be to start spinning and as everything became blurry I would decide where I want to go. Then using my mental image of that location, I would then fully expect myself to be at that location when I stopped spinning and things returned to normal.

And don't worry about not being able to have another LD. You will, no doubt about that. Often it's the first one that may take a while to get, but after that it should be easier as long as you keep practicing what you've been working on, in this case MILD. Just remain confident.
