I’ve also found that journaling without prompts is much more sustainable for me. Now, for the second year, I’m doing daily morning pages of at least 750 words. It takes me about 30 minutes of free-flow writing. I can write whatever comes, and if nothing comes, I write that. It’s helped me to become much more self-aware about what’s going on in my mind and also mostly solved my fear of starting from a blank page.

Initially, I used https://750words.com/ which helped to create a routine. But now I'm using obsidian daily notes with a word counter plugin.
