X. Article Synopsis To forget things on purpose, make a note of the memories you wish to forget and what disturbs you about them. Next, identify objects or pictures that bring back terrible memories, such as photos of your ex or a certain perfume, and eliminate them from your environment. Finally, write down any other memories that come to mind and keep a mental list of things that trigger your emotions. Over time, these reminders will help you avoid storing new memories that might be difficult to erase. So, the best way to forget things is by thinking about them. If you want to remember something, write it down if you can, otherwise just think about it constantly and it'll eventually disappear. The more you think about something, the stronger the memory becomes. So, if you really need to forget something, then try and think of it as much as possible!
