Be wary of those who fetishize the difficulties of their own creative process. One does not need to shirk the healthy levels of their own emotional and physical well-being to make a work that would add meaning and clarity to the world. The human life is composed of such limited currency. Spend it wisely, and in pursuit of a balance of passions.
Take care of yourself.
Such is the contemporary wisdom on work ethic; for the most part a good and healthy redirection of cultural norms. But like any maxim or ideal, it does not apply to all. There are those for whom a life’s balance cannot be struck. Those that, due to whatever mysterious confluence of personal/societal history and chemical composition have created them, for whom work is life. Whether it makes them happy or not. Whether or not they sleep at night satisfied. Their waking moments have been and will continue to be dedicated to that Thing, whatever it may be.
