How do you stick to a habit such as brushing teeth every night, when you’re exhausted?

Normally I would brush my teeth after I took a bath and since I take a bath every night, I also brush my teeth every night.

I check the fabulous app to see how nice it would be to tick all goals complete. Then I also look back at reasons why not brushing could be harmful.
