The Stream of Consciousness/Awareness journaling tool is the most common journaling practice. It allows me to get things off my chest. To empty my vessel of repetitive mental loops. To dive through my stuck programs. To discharge emotions.
Then I can see the worthy gems that were always there but hidden by the noise of everyday thoughts and feelings.
Daily do a BRAIN DUMP – whatever comes to mind write it as fast as you can.
Then read it and write a one line summary.
