Many thanks my friends, I will still try doing it, hoping to induce a LD.
As I mentioned, I just have started keeping notes of my dreams. I know that it would be useless and disappointing LDing without remembering it. I think I am going well with the whole process, though I wanna be neither too confident nor too pessimistic. I have the will of LDing and I know that it will happen, maybe not today, maybe not in one week, maybe not in one month but it will happen and when it happens, I will be ready for it!
