Do the extra work not because you have to but because it's a privilege.
Get in early.
Sweep the floor without being asked.
Especially when it's not your turn.
Not because you want credit or reward. Because you can.
The industrialist wants to suck everything out of you. Doing extra work as a cog in an industrial system is a fool's errand.
For the rest of us, the artist and the freelancer and the creator, we know that the privilege of doing the extra work is the work itself.
The habit of doing more than is necessary can only be earned through practice. And the habit is priceless.
