Habit Stacking

Using an established habit as a cue for initiating another habit. For example, using the fact that you brush your teeth every night and build on it by flossing too. This makes it more likely that you will perform the action and establish a habit.

It also works both ways—not having a consistent cue to stack on top of means you will be less likely to remember to do the second habit.
