The Enneagram, but make it music
Ever heard of the Enneagram?
It's kind of like the Myers-Briggs, but for motivators instead of personality. Maybe you're motivated by the fear of missing out or your own vanity, by the approval of others or the shame you'd feel if you don't live up to external expectations, real or perceived.
Whether when you found your type you shrieked "That's so me!" or wouldn't out of principle explore the topic – the music is worth a listen.
Earlier this year Sleeping At Last released an LP with nine songs, one for each type. It's perfect for putting on when getting some work done.
