Many individuals depend on index cards in their day-to-day lives or jobs. Teachers and students (of all ages, even college) regularly use index cards to create flash cards for learning. Crafters, cooks, and handypersons use index cards to easily keep track of techniques, recipes, and other vital information. Others use index cards for work-related reasons, such as to prepare for speeches, presentations, and job interviews. Index cards are ideal for home use as well, because they can be used to leave messages where others will see them (e.g., taped to the bathroom mirror). And many writers still prefer to use index cards to organize plot points, character traits, story arcs, and other concepts.
