A method for implementing an action-based to-do list includes monitoring user actions with a personal management device which is configured to compare the user actions to a task definition file. A processor of the personal management device determines if the user actions fulfill one or more predefined conditions, within the task definition file. If a condition is fulfilled, the processor of the personal management device modifies the to-do list based on the fulfilled condition. A personal management device for implementing an action-based to-do list includes a user interface configured to allow a user to interact with a to-do list application and a processor configured to execute the to-do list application. The to-do list application, when executed, causes the processor to monitor user actions and compare the user actions to a task definition file, determine if the user actions fulfill one or more conditions within the task definition file, and if a condition is fulfilled, modify the to-do list based on the fulfilled condition.
