jumping on the nostalgia bus

-when you go on a trip, bring music that you've never heard to make nostalgia playlists
When you have no imprint on this new music, you'll be able to create new memories that will revive when you hear the songs later

-keep a journal

-use cues to help trigger memories, imprint and review.
Most childhood memories have only bits and pieces of factual memories, the rest is made up stuff to fill in the gaps.
