Work minus the stress

Stress arises when :
a) one does not do one's duty;
b) one is worried about the results;
c) one is concerned about the 'I' who one thinks is responsible for the results;
d) a,b & c.

The key to success in one's work is:
i) performing duty with perfection in execution - you are giving your best shot
ii) without attachment to the very act itself - 'I' am not the doer
iii) and without worrying about the results - i) and ii) will take care of it.

Everything else will follow.
