Make journaling a habit
Like meditation, yoga, going to the gym, or eating healthy, you will get the most significant benefits when you make your journaling a habit.
First, decide how often you want to journal; it can be daily, weekly, or even monthly. Then find a pre-existing habit or task to associate with your journaling.
For example, the first thing I do in the morning after I have showered and dressed is to sit down with a cup of tea. So, when I decided to move my journaling from the evening to the morning, it was an easy switch to connect my journaling with my tea drinking, and just for good measure, I also slipped in a morning meditation. So now, each morning, I allow 20 mins to drink my tea, write in my journal and do a short meditation before I start my day.
Aligning my new habit, morning journaling, with an old habit, drinking tea has helped me to transition easily into this new morning ritual.
