Maybe you like to draw out what you are thinking, or write it in the form of a poem. Maybe one day a paragraph is long enough to help you clear your head; another day, 10 pages feels just right. There is no right or wrong way to journal, all that matters is that you find a way to journal that works best for you. I know that I encourage you to give journaling a chance. Start without any expectations and just see where the page takes you.
