Here is how to make journaling a habit: link it to something you already do every day, start so small it feels almost too easy, and write at the same time and place. Expect it to take weeks, not days. Missing one day won't undo your progress, so just pick it back up the next day.
A habit is something you do with little thought because a cue triggers it. A 2012 article in the British Journal of General Practice by Benjamin Gardner, Phillippa Lally and Jane Wardle sums up habit-formation advice simply: repeat an action consistently in the same context. Over time, the context itself starts to prompt the action.
A few findings from that article and from UCL's research on habit formation are useful for journaling:
Cues matter. A cue can be an event or a time of day. The authors suggest choosing a time and place you encounter every day of the week.
Small is better. They recommend small, manageable changes, because failure can be discouraging.
Keep it the same at first. The article says variation is incompatible with developing automaticity, so do it the same way while the habit forms.
It takes a while. In the research, automaticity plateaued around 66 days on average, with considerable variation between people. The authors suggest expecting around 10 weeks.
One missed day is OK. UCL reported that missing one opportunity did not significantly affect habit formation. People who were very inconsistent, though, did not form the habit.
Choose a daily cue. Pick something you already do without fail: pouring your first coffee, sitting down at your desk or getting into bed.
Write an "after I" plan. The article's sample plan follows this pattern: "after I have lunch at home I will have a piece of fruit." For journaling, try "After I pour my coffee, I will write three lines."
Start tiny. One sentence or two minutes. You can always write more, but the minimum should be easy on your worst day.
Set up your space. Keep your notebook and pen right where the cue happens. If you journal on your phone, put the app on your home screen.
Keep a simple record. The article includes a daily tick-sheet and suggests rating how automatic the habit feels at the end of each week, from 1 to 10, so you can watch it get easier.
This is an example. Fill in your own cue and minimum.
Cue: After I switch off the kitchen light at night
Place: The notebook on my nightstand
Minimum: One line about the day
Bonus if I feel like it: Answer one prompt
Backup plan: When I'm traveling, I'll write one line in my phone's notes app
Tracking: Tick the calendar each night, and rate how automatic it feels every Sunday
"I keep forgetting." Your cue may be too weak or too irregular. Move the notebook so you physically bump into it, or switch to a cue that happens every single day.
"I don't have time." Shrink the minimum. One line takes less than a minute. Save longer entries for days off.
"I don't know what to write." Keep a short list of prompts on the first page. Good defaults: "What happened today?", "How do I feel?" and "What do I want to remember?"
"I missed a week and gave up." Restart on a natural fresh start. Research described by Knowledge at Wharton found people are more likely to start goals at "temporal landmarks" like the start of a week or month. Next Monday is a perfectly good restart.
"It feels like a chore." Change the format, not the habit. The University of Rochester Medical Center notes there's no set structure: you can write or draw whatever feels right. Try lists, doodles or letters to yourself.
"I'm worried someone will read it." Keep it somewhere private, or use a locked app. You don't have to share your journal with anyone.
Calendar ticks. One checkmark for each day you write. Look at the overall pattern, not the gaps.
Weekly rating. Every Sunday, rate from 1 to 10 how automatic journaling felt that week.
Monthly count. Note how many days you wrote this month, then try to match or beat it next month.
Skip streak pressure. If one missed day makes you want to quit, stop counting streaks and count total days instead.

It varies a lot. In UCL research, it took 66 days on average for a new behavior to become automatic. Expect around 10 weeks, and don't worry if it's faster or slower for you.
The best time is one tied to a cue you meet every day. Mornings suit planners. Evenings suit people who like to reflect and wind down.
Just write the next day. Missing one opportunity didn't significantly affect habit formation in the UCL research. Long, repeated gaps are the bigger risk.
Start with one to five minutes. The University of Rochester Medical Center suggests setting aside a few minutes every day. You can write more once the habit sticks.
