Amused Astoria is meant to be placeholders for a muse. The human brain is not meant to remember things that make you feel good, it is meant to remember things that are dangerous. Like, ouch, the stove is hot, don’t do that again.
If you find yourself connected to a certain muse, bring them home and assign them as a personal muse of what brings you amusement. It can be anything, simple or complex. Focus on things you like rather than love, because there is a difference.
Focus on all of the senses that that joyful moment brings forth. Place the muse somewhere common that you pass by often and practice abundantly to train your brain with what amusement feels like.
