Social media.

I know, I know. I told you to get off your devices, but here it can also be used as a force for reinforcing your episodic memories. Browsing through your Instagram or social media profiles can be a lovely stroll down memory lane, each photo and corresponding caption serving as a powerful cue, triggering recall for what happened. And the chronology of your memories is nicely preserved, assisting your brain in figuring out when things happened. Looking through a photo album or the photos saved on your smart phone will work, too.
