You Need Structure, You Need Predictability, and You Need More of It Than You Think

Psychoanalysts overestimated the degree to which sanity was a consequence of being properly structured internally. The reason that you're sane is because other people can tolerate having you around for reasonably extensive periods of time and will cuff you across the back of the head every time you do something so stupid. Even under those circumstances, mostly what you want is to have a routine that's disciplined, that's predictable, and bloody well stick to it. You're going to be way healthier and happier and saner if you do that.
