Human life is a [dynamic] . Everyone, therefore, must have a b [plan] to do something or to be something in life. And that is one's c [aim] in life. A man without an aim has no d [direction] and can never go ahead as expected. So everyone should choose a e [profession] which f [suits] him most. The choice of profession depends on one's taste, interest, g [aptitude] and ability. These h [vary] from person to person. Teaching is a noble profession. The teachers are nation-builders. They i [educate] the children and train them to become good and useful j [citizen] in future.
