The best advice I can give you is for you to have patience.

You seem to be doing pretty well already, but LD success varies greatly from person to person. Just keep reading the tutorials, practicing new techniques, writing the journal... etc.

4 days is a very short period of time, so don't be discouraged for not having had one yet. It may take a little longer, and maybe even a lot longer (hopefully not). Anyway, just keep at it... and best of luck to you!

How is your dream recall by the way?
