You seem to be stressing way too much, and probably just lack the confidence/belief that you will have a lucid. I tried for 6 months on and off to get a lucid, and then I got like 7 in the past few weeks. If you are focused and belief they will occur, they will. I used only WBTB and MILD, and I got a few random DILDs too. Everyone is capable of an LD as long as they do dream.
