Maybe I’m an odd duck, but my key trigger to brush my teeth is an aversion to how gross my mouth is if I don’t, not habit. The reward is immediate, and the task fast. Noticing my mouth is gross catches any failure of the habit of teeth brushing in my routines. The habit developed from repetition but is very much not necessary to get me to do it, there’s an actual, natural, reliable trigger for it independent of the habit.
