I physically kept track of my consecutive day streaks... maybe gamifying it for myself in a sense. But I wrote down the date that I started and put that paper in a safe place. If I miss a day, I start a new sheet with a new date and start over but I keep it in the same place. It took me a few months to hit 30 days, another year to hit 100 days, and I rolled past my 1000 days mark like a year ago and it hasn't been that hard to keep with it since. But I still got my sheets stashed away.

The 30 days, 100 days, 1000 days mastery I got from my yogi who taught me kundalini yoga. She said it's basically a habit after 1000 days in a row. Good luck!
