How can we work enthusiastically if we are to be detached from the fruits?

From: sharmistha

For most of the newcomers for kc when we start dovetailing our activities esp for student it really becomes difficult sometimes to work hard for academic performances and yet not get attached to the results…..because of our conditioning most of us have the tendency to work really hard for the object of our sense gratification but when we like to see the same object not a object not as that which satisfy our  senses then the vigour of work to get that comes down and hence is performance…how to overcome this?
