Make a playlist.
Curate a collection of artists and songs that surprise and delight. Include unexpected combinations; choose something you've never heard before alongside an old favorite; include a deep track from a favorite album. Instrumentals and acapellas. Rock music and musical theater. Throw in something that makes you laugh, and something that makes you sing along at the top of your lungs. Play it loud and play it often, and then make another.
I ought to do this once a month, but I nearly never do.
Here's mine from today, if you're interested.
