Find Your Grace
Maintaining your equilibrium over time is crucial, recharging the batteries, etc.
I've got a couple of habits that help me with this.
The first is a set of sanity-restoring activities, like going for a walk, or prioritising sleep, or learning something new. I try to do something from this list daily.
The second is something that the French enforce by law — taking at least two weeks of vacation all at once. At first glance it seems bizarre that some of your holiday pay is constrained and that you must take it in the months of July and August each year. That's partly why the whole country seems to shut down just as the tourists arrive.
But getting away, going to somewhere that you can sit by the bonfire and chat with your maiden, that's golden.
