I think there are some more - fresh air and sunlight (high CO2 indoors is detrimental to cognition and sun is needed for the circadian rythm and vitamin D and other stuff) - social contact (appropriate to personality), so friends, family and romantic relationships to the extent and intensity that one's personality needs them - career success and stable finances: makes one feel useful and takes away a lot of stress and frees up mental energy to think about all the other things mentioned in the article - winding down sometimes, unplugging from phones, TV etc. One way is meditation, but can also be just sitting with a cup of tea thinking about nothing particular - learning and trying new things, new foods, new languages, new books or genres - challenging oneself and overcoming discomfort, physically such as cold showers, or mentally such as public speaking or whatever seems scary/hard I think the overall idea is a scaffolding of routine and stable structure in life punctuated with deliberate, planned and conscious reaches out of the comfort zone. Like yeah waking up every day is great and much better than a whacky schedule. What's probably even better is having exceptions and whacking up your sleep for one or two weeks per year for a festival or a hike or a few days of intense creative work. The point is to return to the default every time, but religiously sticking to a rigid routine where you cancel and refuse anything that may conflict with it is only to be recommended to people with really low change tolerance like certain autists. Even they should play with their own limits even if those limits are at a different place.
