Try not to fret in this frozen city, Aristotle can help you find happiness without (much) reference to the weather:
For some people think that happiness is a virtue, others that it is practical wisdom, others that it is some kind of theoretical wisdom; others again believe it to be all or some of these accompanied by, or not devoid of, pleasure; and some people include external prosperity in its definition… the presumption is rather that they are all right in at least one or even in most respects.
– Aristotle, Nicomachean Ethics (1.1098b23), trans. Martin Oswald
