My first lucid was pretty long because I basically had no expectations for the first one. I treat dreaming as a gift. When I wake up from a regular dream I don't groan that I didn't have a lucid, I'm just happy I had a dream. I know the lucid will come with time. Basically when I was thinking of what to do in my first lucid I just decided to make sure to stabilize and reality check, no flying goals yet and such, I know I'll have more.

So when I became lucid finally I didn't do anything but rub my hands together, I did this nearly every 15 seconds. Until I felt stabilized enough I walked around and looked how real everything was, still stabilizing. Eventually I came around to the back of my house went out m second floor window and jumped What can I say? I wanted to see what would happen, and I woke up.

So basically don't expect to do all this amazing stuff in your first lucid, try the basics and build from there
