Kurt Vonnegut Jr. said this quote

What I had to say to you, moreover, would not take long, to wit: Practice any art, music, singing, dancing, acting, drawing, painting, sculpting, poetry, fiction, essays, reportage, no matter how well or badly, not to get money and fame, but to experience becoming, to find out what’s inside you, to make your soul grow. Seriously! I mean starting right now, do art and do it for the rest of your lives…. You have experienced becoming, learned a lot more about what’s inside you, and you have made your soul grow.
