Journaling is something that allows you to focus purely on yourself and your thoughts, which is harder and harder to come by in a world of increasing technology. It can be beneficial for mental health because if you are writing about positive things in your life or things you are grateful for, in a sense you are experiencing and enjoying these events for a second time. I encourage many clients to keep a gratitude journal because when you are thinking about what went well, you spend more time focusing on the good.
Journaling has some amazing benefits at the time you are doing it—but it’s also a gift to your future self. You are preserving your thoughts and emotions that you can come back and see again at a later time. You can decide later if you want to keep it for future generations or if you never want anyone to see it. If you decide to keep it, I think you will see so much change in yourself over time.
