"Better is one's own duty, though devoid of merit, than the duty of another well discharged. He who does his own work does not incur sin."
Modern explanation
In the middle of the day, return to this: The work that fits your nature will tire you in a way that still feeds you. Borrowed work only drains.
Practical application
Audit the last three hours: which task most belonged to you? Do more of that.
Reflection question
What would change if I treated this ordinary work as sacred?
