Resist any unnecessary systematization of human interaction. Be especially wary of the dealings with those you have little in common with.
When the food clerk asks you what you want to eat, reply with “good, how’s your day going?” When the receptionist asks you to fill in a form, say “very cool, any plans for the holidays?” And when you and that person you pass everyday get stuck on the topic of daily weather, break the mold with “yeah but watch out for those volcanoes and asteroids man.”
In fact, when anyone broaches you with too much utility, respond with too much extravagance. Human interaction, as much as possible, should be a creative act between two or more minds. We can only handle so much monotonous dialogue before considering a life of forced monasticism.
