This is an interesting concept. It's reminds me of similar techniques I'd use to compose rituals, inspired by the automatic drawing/writing techniques that I read about A.O. Spare.
I usually keep a variety of journals, for different purposes or moods. Maybe I'm just very gemini, but if I only keep one journal, then I get too picky about what I write in it. If I have an official grimoire, along with a poetry notebook, a dream journal, and another pad I use to scribble things and sigils in occasionally etc, I find that I don't hesitate as much to record random moments of possible insight.
Anytime I think of something that I feel is particularly meaningful, I'll try to write it down in a way that captures the feeling of that particular experience so I can recall it later. When enough of these things happen, I'll read over them and look for patterns or themes that can be seen through the looking glass of long periods of time that aren't apparent in a moment by moment state of mind. Like a bird's-eye view of your summer as opposed to the ground level view of a weekend in June. And sometimes the intuition will piece together a message that gives me goosebumps or just feels right to me in an esoteric sense, and from there I'll organize a ritual (or artwork) to help materialize that feeling in my own life, coming from a place that's hard to find in everyday consciousness.
I'm sure there's parts I'm forgetting to explain but I have a tendency to rant and convolute, so I'll keep it concise
