I think there is a balance that we strike individually and collectively, between good and evil, right and wrong, up and down, happy and sad. Like all species we follow rules that result in benefits, survival, which is good and avoid punishment, pain or death, which is bad. We live by rules, some written, laws, and others unwritten, morals, ethics, integrity, courtesy. But those rules change with the times. It seems like decorum and civility disappeared with Social Media, and the ability to say things online in a public square, anonymously, that you’d never say in real life, because of the real social costs. That’s a double edged sword, which cuts both ways.
Adding the word happy to medium to get the fabled "Happy Medium" as an ideal is actually just an admission of being spiritually lazy.
In truth it is the Safe Medium as in playing it safe and working both sides of the room. It also represents the Luke Warm that even the also fabled Jesus spit out.
So yeah there is a middle ground, aka, checking out, that may keep the stress away of really going for it, but it dulls one's spirit and leaves one on the sidelines.
As I noted in another thread, "compromise" between Hitler and old German values resulted in good but weak people arguing over how many Jews should rightly be killed; over whether gypsies should be executed or just sterilized.
Compromise, centrism, moderation as a moral standard gives decisive power to extremists.
