It took
me years (not saying it does for everyone) because 1) I didn't
fully dedicate myself to do it. I would go months without trying (I do have a life, and most nights I go to bed exhausted), but would have lucids dreams, anyway, and 2) I tend to stress a lot, and stress
(for me) impairs my ability to become lucid.
You cannot go around saying
it took me three days, so it shouldn't take you long either; that's like me throwing my youngest daughter in the pool and saying
it took your brother two days to learn how to swim, it shouldn't take you that long either. Everyone is different. We don't all have the same brain.
The bottom line is: LD'ing is different for everyone. Good for you for being a natural.
That's your opinion.
