Go into the arts. I’m not kidding. The arts are not a way to make a living. They are a very human way of making life more bearable. Practicing an art, no matter how well or badly, is a way to make your soul grow , for heaven’s sake. Sing in the shower. Dance to the radio. Tell stories. Write a poem to a friend, even a lousy poem. Do it as well as you possibly can. You will get an enormous reward. You will have created something.
If your friend is passionate about something, then it’s important to you too: because this is important to your friend. You don’t have to get it, but don’t be the one who rags on it. Why would you even do that? Why strangle a voice? Why dampen passion when there is so little of it in the world? Rejoice with those rejoice, mourn with those who mourn, and maybe you should join your friend on that adventure.
