My journaling template isn't much and it does not require much. Be open to the idea and with yourself so that you can reap as many benefits as possible from keeping a journal!
MY PERSONAL JOURNALING PRACTICE
MORNING: WAKE UP, WITHIN 10 MINS I'M SITTING AT MY DESK JOURNALING.
Pour a cup of coffee, let the dogs out - or whatever your morning routine consists of - and then sit down to write. Start with what you're grateful for.
I'm grateful for XYZ today and it's because of this reason and that reason and so and so on.
I'm grateful and happy that I have XYZ in my life and that I'm able to give to QRS, etc.
I'm grateful that the first two examples are likely enough for you to get the idea :-)
