This is something that has bothered me for a long time. Modern Psychology says that motivation is required to do any action - be it to drink water (thirst is the motivation) or to crack exams (achieving good marks is the motivation). Whatever it is, modern Psychology seems to push a more goal-oriented lifestyle.
However, Karma Yoga seems to suggest the opposite. It tells us to do our job without any attachment to it or to think about its fruits. Isn't this absurd? Without a proper goal and motive, what will inspire a person to do anything? Bhagavad Gita tells us to take a disinterested view of our work. However Psychology says that passionate work, done with love, curiosity and emotions result in better work than disinterested work. A cloth made with love will be much more beautiful than a cloth made by a disinterested person (which is why sweets made by our grandma tastes better than cookies manufactures in bakeries).
So doesn't Bhagavad Gita go against Psychology in its suggestion of pursuing disinterested action? If employees start working without emotion in their work, in a cold disinterested fashion, it might lead to lower GDP growth as efficiency will naturally decrease.
