 You would have noticed that many a times dogs chase, run after, speeding vehicles, cars, motorcycles, etc. A farmer had a dog who used to sit by the roadside waiting for vehicles to come around. As soon as one came, he would just run down the road, barking and trying to overtake it. One day a neighbour asked the farmer, Do you think that your dog is ever going to catch a car which he is chasing, running after, trying to overtake? The farmer replied that that is not what bothers me. What bothers me is what he could do if he ever caught one. Many people in life behave like that dog who is pursuing meaningless goals. Be very clear about your goals in life and career. Don't be impulsive or random. Those efforts will just waste you completely. Life is hard by the yard as they say, but by the inch it's a clinch.
