There are two ways to achieve this.
The first is take the weight away. To refuse to do work that’s important. To not care about the outcome. Whatever.
The second is to eagerly embrace the weight of our commitment but to commit to being light, regardless. This is the surgeon who can enjoy doing brain surgery, not because surgery isn’t important, but because it is.
The work is the work, regardless of whether you decide to be ground down by it.
It might be tempting to try to relieve yourself of responsibility, but it’s a downward spiral, a path to banal industrialism. Better, I think, to learn to dance with it.
To take it seriously, not personally.
