There was a misunderstanding due to your previous comments which were a little bit confusing.
I understand what you're saying here, basically over time you will start doing it without even thinking about it, your "subconcious" takes over. Could even call it "state of flow" or something like that :D .
I agree to some extent. I think you need to focus every time you want to LD, if you look at most- different techniques are implemented by people (even experienced dreamers) to induce LD. Even then, there's a chance that you might not achieve it. Nevertheless, it's true that your mind will eventually adapt to the common reality checks and all day awereness and will ultimately do the same while dreaming (which will increase the chance of LD).
