Thanks for the remark. Here's how a tickler file works:

The system consists of two types of folders: dayly for in the running month and monthly folders for the year.

You can place all short-term items into the appropriate daily folder to schedule them for the current month. Items which need attention in a future month are put in the corresponding monthly folder. This makes the fortythree folders one of the easiest to use follow up systems.

Every day, you can focus on those items, that you have commited yourself to for that specific day. At the end of the day you can enjoy the feeling of achievment, when everything is done. Open tasks move to the next day.
