"Therefore, always perform without attachment the work that has to be done; for performing action without attachment, one attains the Supreme."
Modern explanation
When the day pushes against you, remember: Purpose is not a destination you reach; it is a quality of attention you bring to ordinary work.
Practical application
Do the work even when motivation has left the room. Discipline is borrowed motivation.
Reflection question
What would I do if I knew this work was preparing me for something I can't yet see?
