Instead of trying to remember a specific thing that you have to do—such as repaying money borrowed from a coworker—visualize a scene in which you actually are doing it. Example: Imagine taking the money out of your pocket or purse and handing it to the coworker at a specific location, such as the break room. Create the visualization before going to sleep—your brain will strengthen the image overnight, and you will be more likely to do the task the next day.
