Read through the tutorials here on DV, they are very informaitve and the folks put alot of work into them. Once you employ the techniques then luck will come into play to a certian extent. You might want to try isochronic tones and binaural beats. I recently started using them and went from 2-3 nights a week to 5-6 with most nights having multiple LDs. The key is to not rely on one thing only, especially luck. As for enjoyment, i dont have the words to express the level of gratification I get from LDn. The euphoria from a good LD can last for days.
