Not wanting to
Admission: every night, I look into the bathroom mirror and think to myself, “I don’t want to floss.”
Then immediately afterwards, I floss my teeth.
It’s amusing to me that the trigger for my habit is my thought of not wanting to do the thing.
Some good habits are formed not by falling in love with the task, or earning a reward, or being otherwise compelled. They’re formed by consistently taking the right step even when you acknowledge that you don’t feel like it.
