I added above about habit stacking. The idea is to lump a new habit onto an existing habit, which makes it so much easier to stick with. For example, when you brush your teeth in the evening, do your Duo lesson. Or, when you go make a cup of coffee add a new habit in during the three minutes it makes to boil the water.
Here’s a random article that explains it: https://health.clevelandclinic.org/habit-stacking
I also have an orange cat that does this, though not to such an extent. What is the connection?
