I promised to do a proper list of my stress resistant cheese slices, so here goes.
Music
Choir business is serious business. Although it also causes stress at time (I'm acting in the board of the choir etc.), singing is a huge source of energy and joy. Only thing that overrides choir stuff is family. Everything else is secondary.
Hole: Choir business is serious business and sometimes takes a lot of time, energy and effort. Just have to keep alert about situations when general stress is high and at the same time choir business peaks up. At that point might have to cut down a bit and try to delegate something or even (gasp!) skip a concert or an exercise.
Exercise
Keeping physically active is obviously a good idea. It takes practically no time and the energy it gives is astonishing. If day has 15-30 minutes of extra, I can squeeze in some exercise. And a day always has 15 minutes of extra.
Hole: Sometimes you are just so spent, that you can't pay the small cost of exercising to get the big boost of energy afterwards. Just have to keep alert about these times and try to slip in a light stretching session while watching TV or something.
Walking
Walking is just enjoyable. You both get out to look at nature, don't get sweaty and get steps tracked on an app. All good and important things! So if I'm stressed out and can't do anything else, maybe I can go for a small walk around the park.
Hole: Walking takes more time than basic exercise. So it's easier to skip it or forget it. Also, this is something I haven't really done before, so it will take some doing to get used to doing it.
Sleeping
Sleeping is mandatory. I don't seem to need a whole 8 hours a night to function, but it really doesn't hurt either. Guideline for sleeping is at least 20 hours per 3 nights. That I could probably keep up nearly indefinitely without breaking down and would still let me skip half of one night's sleep to finish up something before a tight deadline. Still about 8 hours a night is the normal goal.
Hole: The danger is just not following this guideline. I don't have much trouble sleeping usually, so I'm not that worried about the "can't sleep because of stress" danger. I'll think up something if that starts worrying me.
Meditation
Meditation has seemed like a brilliant tool, so I'm keeping that habit. You just can't work effectively for straight 8 hours for example. 15 minutes of meditation in between should act as a brilliant way to get a breather.
Hole: As a new habit, it's hideously difficult to remember to take those 15 minutes. Good time management tools could maybe help about this, but using those would be an even newer habit for me. Might have to test those out at some point though, I'll add it on my to-do.
Family
At least 24h time for the family a week. I haven't really been in a situation when this would have been a problem, but it's easy to imagine a scenario when even this sort of elementary stuff would break down.
Hole: Hopefully I don't have to start measuring or adding up hours with the family, but it might still be a good thing to have a sort of hard limit decided. As a wake up call, if nothing else.
That's my list for now. There's no relaxation, watching TV or anything like that on the list, as those I will do anyways and usually that sort of things don't really give that much energy back. They just are something so low cost, that you default to them when everything else seems like too much. This list will hopefully help me default less and invest more into stuff with higher ROI, even if you do have to pay the cost in energy, time and effort in advance.
