Well, I think that when you have experience, it puts you in a different category, because you didn't try to LD for 20 years before lding, and you didn't have many lucid dreams.

If I don't try before I go to bed and wake for wbtbs and micro wbtbs, I quickly lose lding ability and recall drops to one dream. I have to at least do night work. I think that when focusing on dreams too much, you can get stressed easily, and stress kills dreams.
