most working actors have day jobs in real estate, have family money, or a spouse with a real job. i met someone whose breakout lead role was in a $70M budget film that flopped; they were driving lyft two years later. people have no idea how precarious the arts are.
There is nothing wrong with shitty substacks, music, art, film and the like. People need to creative outlets because they help you confront parts of yourself that you have been avoiding.
