It takes some people months to have their first lucid dream try to be patient, even though its hard.
It's good that you remembered that many dreams and started a DJ, it will help a lot.
Try not to stress yourself about it, it seems like you are over working yourself, but don't, just try to be chill about it, because if you stress yourself with it, you are less likely to have an LD because tension and such about it will just hinder you.

There is really no way to know how quickly you will have a lucid dream, you just have to stay persistent and one will come.

good luck~
