I am happy that I have started my dream journal again. Though it does get annoying to write in it after waking up--I am groggy and prefer to just go back to sleep

I honestly have no trouble remembering my dreams. One morning I didn't want to write in the journal until I was awake with my cup of coffee and had no problem writing down the dream details as I watched TV. My question is then--I really want to start trying to achieve lucid dreams and do I need to then keep my dream journal going to do so? Is it vital to write down all dreams?

Someone had told me that I should first take these steps to dream control very slowly. I should first do a dream journal for at least a week. Then work on lucidity. But can I just start working on lucidity right now?

Thanks for the help!
