I gained a lot of appreciation for people who make things, and lost a lot of tolerance for people who only pontificate. I found myself especially frustrated with my past self, whose default was to complain and/or comment, then wonder why things didn’t magically get better.

The first emphasis in Make Fewer Things Matter is “make.” Things don’t stop mattering on their own. You don’t just ignore them. You do something to make them not matter.

The next emphasis is “fewer.” Some things will still matter, but you reduce the number of them. Make a big list of things you think are important. Look at each item and look for ways to make it not matter.

After you go through everything and you try to make them not matter, you’re left with a few things that truly matter.

Of course most people are not car mechanics or airline pilots. Most people have jobs where being a "moral idiot," as Crocker puts it, won't kill anyone. Should we really demand that the guy who checks ticket stubs at the movie theater hones his craft?

Well, yes. No job is too low to not warrant care, because no job exists in isolation. Carelessness ripples. It adds friction to the working of the world. To phone it in or run out the clock, regardless of how alone and impotent you might feel in your work, is to commit an especially tragic -- for being so preventable -- brand of public sin.
