I'm not so sure. Meditation is obviously great but I think that people over hype it. I meditate daily but really I don't think it has that much effect on my lucidity. The most effective thing for me is definitely WBTB. I think LDing is more about brain hacking and that's way more complicated than brute force psychology on its own. How mindful I can be awake isn't really going to mean much if parts of my brain are shut down when I'm dreaming.
