Motivation and Karma both are entwined
While building a nest, a bird never gets exasperated even it has to make strenuous efforts due to the vagaries of weather like heavy rains or dusty winds or even it faces any assault on its nest by any other animal, bird or man. But it does not give up and continues unmindful of these obstacles, by which it can be adduced that there is a direct connect between motivation and sincere and honest efforts.
