It's just physically, psychologically, and logically impossible that EVERYTHING is THAT important. But we are bred or nurtured or trained to think it is. This Western thing isn't work ethic--not really. We have that, for sure (ask this old-time Yankee--I hear you about the work ethic), but we carry something else, too--this sort of guilt/responsibility thing that tells us if we're NOT panicking about getting x/y/z done, then we're, what? Worthless? Or, rather, not worthy to be employed/educated/loved?
Well, let me tell you something--you paid for your ticket here, this incarnation. You're paying with your intelligence, your compassion, your empathy, and your attention. That's enough. Do what you can. Be honest with what you can handle. Let the rest go.
You may be surprised to remember that no one actually owns you. (You might get pissed off, too, but that's a post for another day...).
