A couple Tape. I own 10 different types of tape. Duck tape, the rainbow colored one, is great for visual identification + slight adhesive. You can just take your keyring / keyfob/ roll a few inches of 1" wide tape, it has many uses. 1. Have an idea at night → dump a stickynote with tape on doorknob, remove it morning → logit in computer notetaking platform 2. Have an idea anywhere → take a stickynote, dump it in your wallet → logit in computer 3. Important reminder to do something? → place it in associated location. E.G. if you need to bring backpack to work tomorrow, clip your wallet onto it. E.G. Need to reminder yourself something tomorrow? Throw a stickynote inbetween keys on keyboard. E.G Need to call someone in the morning → stickynote a reminder on your phone in morning. Done, I strongly don't believe in a todolist app, it adds no value. Discipline is life. Simple is better.
