I've been waiting all year for this day and it's finally, finally here: Checklists Day! Right now, I have a checklist for packing which comes in handy. I made up the list because I got tired of having to create a packing list every time I was traveling.
This morning, though, I thought of some additional actions that could be checklisted -
Time based occurrences - daily, weekly, monthly, yearly events/obligations
Long term projects/goals
Reminders before leaving the house - make sure you have keys, wallet, needed material; electricity is off
Packing a gym bag
Preparing for an errand
Visits to the doctor - have medical card; lists of medications, questions and health concerns with you
If you're in business, you could also create checklists for marketing yourself, maintaining your social media presence and so on.
