Start with modest goals, once or twice a week. Build towards every day, at least once a day flossing. Floss wherever and whenever, in the shower, watching TV, listening to music. Make it a routine, floss at the same time each day. Keep floss handy. For a cleaner, fresh-breath feeling. For sensitive gums. For limited manual dexterity and first-time users.
