One way to process your day is to collage it.
Take some bits and pieces of your life and arrange them.
Maybe add some color and words.
This is profoundly gratifying, in part because it makes beauty out of the daily stuff we have to deal with, and partly because it validates that play is worthwhile, and your brain while playing accesses some other, deeper place.
Repetitive drumming, meditation, being in Nature; we all have ways to connect, try making a collage in that state and see what happens.
"An artist doesn't really create anything - he just rearranges what is already there." --Paramahansa Yogananda
