I use fabulous to remind myself (hopefully soon it will be habitual). Then I think about how much I gain from reflecting on my day or writing out what I want to achieve that day, who I want to become. I find thinking about making myself a better and stronger person is motivation enough!
I put the writing in my journal a habit and I feel much better after listening to the writing guide. Without the guide, I would put off writing. So using the guide keeps me motivated and less overwhelmed than when I write by myself. Without the guide I feel like I could spend hours writing., so I put writing off for days.
