- Hand washingEvery time you get home, wash your hands with soap and water before you touch anything else
- Headphone volumeTurn it down until you could still hear someone talking beside you, and leave it there. A percentage of maximum volume tells you nothing about how loud that is
- Not cleaning between your teethAdd flossing to the brushing you already do
