You have the right to work, but for the work's sake only.
You have no rights to the fruits of work.
Desire for the fruits of work must never be your motive in working.
Never give way to laziness, either...
Work done with anxiety about results is far inferior to work done
without such anxiety, in the calm of self surrender...
They who work selfishly for results are miserable.
-from the Bhagavad Gita
