I don't understand my brain.
Sometimes it's really good to me. In the past, it's given me Heath Ledger on a beach in Hawaii. So I know it is capable of great things.
But why is it when I try to go lucid, it never happens?
I've been doing my RC's faithfully. I've been aware. I've talked to myself before going to sleep. Nothing.
But if I don't think about it, don't bother, LD's just come out of nowhere. Is there some kind of science to this? Or am I just more stubborn and difficult than I realize?

Any hints, tips, suggestions?
