Something I learned the wrong way (via burning out hard):
There are 3 “zones” in a company:
0: your direct impact zone (where you can just _do_ stuff)
1: indirect impact zone (you can convince/bribe/blackmail people into doing stuff)
2: the rest of the company
IMO, the key to keeping some kind of sanity is to bin the issues you see around into one of those 3 zones and act accordingly. And that sometimes means you need to just let something you deeply care about go, just because it’s in zone 2.
