Improve your ability to remember things

Create a “memory palace” in your mind to remember specific items.
Our brains naturally are inclined to remember places we’ve been. In your mind’s eye, recall a specific, familiar place. At each marker – say, room corners or from the front door to the mailbox – place your item(s) and make them be occupied with imagery. 
Example: If you forgot your to-do list and want to remember getting cat food easily, imagine yourself opening your mailbox to find a cat inside.

Make the memories outrageous.
To make your memories stick more, use funny, sexy, crazy, or disgusting imagery to what you’re trying to remember so you’ll have an easier time remembering.

Test yourself.
To strengthen your retrieval, ask yourself, "What did I just learn?" or "What was her name again?" as soon as you learn something new, such as a new person's name. Consider using "spaced repetition," a method of intentionally recalling a memory right before you feel you forget it.
