Once there was a farmer who had a goat and a horse. One day horse become ill so farmer called veterinarian. Vet said, "Your horse has a virus. he must take medicine for three days. I will come back and give him medicines for three days and on third day if he is still not better we have to kill him."Goat listened to all this conversation. Next day vet started medicine for horse. Vet gave him medicine and left. After vet left goat approached the horse and said, "Be strong my friends or else they are going to put you to sleep forever."Similarly on second day vet left after giving horse medicine. Goat came to horse and said, "Come on buddy get up or else you are going to die!! come on get up..!!"On third day, after giving horse medicine vet examined horse and said to farmer that, "Unfortunately we have to kill him. otherwise the virus might spread and infect other horses."This time after vet left again goat came to horse and tried to help him. Goat said, "Listen friend, its now or never!! get up, come on have courage!! come on get up!! that's it, come on get up slowly. great! come on, one, two, three, good rum faster..!! run run more!! yes, you did it!! ow you are champion.."All of sudden the farmer came back, saw the horse running in the field and began shouting, "Its miracle! my horse is cured. we must have a grand party. lets kill the goat." This often happen in life and work place. No one truly knows who deserves the merit of success and contributing toward success. Who is actually contributing the necessary support to make things happen. Be grateful.
