what i learned at my internship

Tickler file: a date-labeled file folder organized in a way that allows time-sensitive documents to be filed according to the future date on which each document needs action. Each day, the folder having the current date is retrieved from the tickler file so that any documents within it may be acted on. Essentially, a tickler file provides a way to send a reminder to oneself in the future—"tickling" one's memory.
