One day a man went for a walking walk, only when he saw a boy taking a garbage in a street, two or four dogs were roaming around him. That man gore one thing of that boy, seeing that dogs barking, there was no fear on the boy's face nor the boy had any attention on those dogs.
That boy was just working to raise his garbage. After that the boy went from there to the second street and the dogs of the other street also started boring after seeing him. Even there, the boy continued to work on raising his garbage by not paying attention to the dog.
That is what you should adopt in your life. The saying is 'listen to everyone's mind' listen to all of you but only do what your mind wants. With that you will be able to do that work with full dedication and perseverance.
