Make a list to remember what you need to take. Headed on a Photoshoot? Make a list of all the equipment you'll need so you don't forget anything. Whatever you're doing, make a list so you don't forget anything. Make reusable lists. Add items to them. Review your list before you go somewhere or do something. Check off the items you've got ready. Next time you need the list, just press the reset button and all the items you checked the last time get unchecked and you're ready to start again.
