How do you write a Stoic journal. As absurd as that sounds how can i make my journal something that will change my life?

I read somewhere that journaling can feel fruitless or aimless at times but it’s that it’s anything but that, and after a time, it will inform every aspect of your life. I find that to be true. I feel much more in tune with my ‘best self’ LOL. Sounds silly but it doesn’t feel so; it’s hard to put words to. I feel much more able to express myself authentically and to show up in my life wholeheartedly and without fear or shame.
