Making art is valuable because it reveals the artist.
You are the myriad decisions and intuitions that go into the making of the piece. When you look upon (or listen to!) a piece of art, you are looking at the material embodiment of the artist.
The ability to transfer your thinking, and what some would call soul, into inanimate objects is a minor expression of the divine. You literally breath your life into it.
I took my 4 y.o. daughter to see the Frida Kahlo exhibition a year or so ago. She stopped in front of “The broken column (self-portrait)”
She started tearing up, and looked like she was about to cry. I asked her why, and she said, "she hurt so much". Indeed Frida did, and 70 years later, in another country, a little girl felt her pain for a moment.
Art making is amongst the most profound human activities.
Everyone should make art.
