First, if ya think ya can't then ya can't. Works that way for everything in dreams, think ya can and you will. To stay lucid is simple, just keep your focus. That is all being lucid is, nothing else just focus.

As for SP, ya don't need it to wild just enough focus to stay concious till the dream. I mastered lucid dreaming when i was a kid, i just never used it before. My dreams tend to be to weird even for me, so i never try being lucid.

I should try it sometime, then maybe i could get a dream i actually want.
