There are uncountable great people in the world. Be it our parents, who sacrifice their likes and dislikes and do not live in luxury to provide the children's needful to the brave soldiers who give up on their families and fight at the country borders to save their nation.
Not to forget the great people who have made infinite successful and useful discoveries and inventions which have made everyday life easier for the people.
The farmers are also great people who work hard day and night to produce grains, crops, vegetables, fruits, and all types of food so that the people in the world can have food.
The doctors who save people's lives, the teachers who teach the children to learn and grow into responsible citizens, the leaders, like APJ Abdul Kalam, who work for the welfare of the people, the volunteers and organizations like Mother Teresa and her missionaries, who support the downtrodden, helpless and the sick people, are all great people.
