Practice any art: music, singing, dancing, acting, drawing, painting, sculpture, 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 will find that you have already been gloriously rewarded. You have experienced becoming, learned a lot more about what's inside you, and you've made your soul grow....
