A journal helps me in life frequently.... what do you put in it? Anything you want! But to me, journaling or writing down things I'm grateful for.... sober people I want to be like.... things I value in my life and want to be the priority (over booze and drugs).... Journaling in the morning helps set the intention for a sober and present day. Having a few priorities for the day that I"ll honor. AA was helpful for me, but I used it as one of many tools. The Big Book was helpful for me..... I read it over and over (especially the personal stories).
Basically - anything and everything you can do to keep your head in recovery and your eyes on the prize(s) that you WANT your life to be about.
You can do it!
